- Such treatments and/or coatings can be used in the case of metal cans, wherein the treatment and/or coating is used to retard or inhibit corrosion, provide a decorative coating, provide ease of handling during the manufacturing process, and the like.
- Coatings can be applied to the interior of such cans to prevent the contents from contacting the metal of the container. Contact between the metal and a food or beverage, for example, can lead to corrosion of a metal container, which can then contaminate the food or beverage. This is particularly true when the contents of the can are acidic in nature.
- the coatings applied to the interior of metal cans also help prevent corrosion in the headspace of the cans, which is the area between the fill line of the product and the can lid; corrosion in the headspace is particularly problematic with food products having a high salt content. Coatings can also be applied to the exterior of metal cans.
- the coating compositions are particularly applicable for use with coiled metal stock, such as the coiled metal stock from which the ends of cans are made (“can end stock”), and end caps and closures are made (“cap/closure stock”). Since coatings designed for use on can end stock and cap/closure stock may be applied prior to the piece being cut and stamped out of the coiled metal stock, they may be flexible and extensible. For example, such stock may be coated on both sides. Thereafter, the coated metal stock is punched. For can ends, the metal is then scored for the “pop-top” opening and the pop-top ring is then attached with a pin that is separately fabricated.

After cooling the sample solution, the excess acetic anhydride was converted to acetic acid by hydrolysis by adding a 20 mL solution of dimethylformamide, pyridine, and distilled water (3:1:1 volumetric ratio) to the above mixture. The resulting solution containing excess acetic acid was titrated potentiometrically with 0.5 N methanolic potassium hydroxide solution by using a Metrohm 904 Titrando. The volume difference, in millilitres, between a blank determination (0 grams of sample) and the sample determination corresponds to the hydroxyl number of the sample.

The sample of polymer (0.1-3 grams depending on hydroxyl number) was weighed accurately on a balance with accuracy to weigh in milligrams. If the polymer contains acid functionality then the hydroxyl number was corrected by the addition of the acid value with the measured hydroxyl value. Where the sample of polymer contained an alcoholic solvent, the hydroxyl number was corrected by subtraction of the hydroxyl number corresponding to the weight percent of alcoholic solvent.

- Emulsion polymerisation may be carried out in a suitable reaction vessel. The emulsion polymerisation monomer component, initiator and/or water of the emulsion polymerisation reaction mixture may be added to the reaction vessel in any suitable order. For example, the water may be added to the reaction vessel before the emulsion polymerisation monomer component and/or initiator are added to the reaction vessel.

Adding the emulsion polymerisation monomer component over the aforementioned time periods may result in an emulsion polymerised acrylic latex material that displays lower agglomeration than may be expected.
- The emulsion polymerisation monomer component may be added at any suitable rate during the time period for addition of the emulsion polymerisation monomer component. The emulsion polymerisation monomer component may be added at a constant rate or the emulsion polymerisation monomer component may be added at a variable rate during the time period for addition of the emulsion polymerisation monomer component. The emulsion polymerisation monomer component may be added dropwise. By the term ‘dropwise’ and like terms as used herein is meant, unless specified otherwise, that the emulsion polymerisation monomer component is added at a rate of from 0.05 to 1.0 wt %/minute over a period of time, T, based on the total solid weight of the monomers in the emulsion polymerisation monomer component. The emulsion polymerisation monomer component may be added at a rate which results in a low level of free monomer in the emulsion polymerisation reaction mixture. The emulsion polymerisation monomer component may be added at a rate which reduces or substantially prevents the monomers of the emulsion polymerisation monomer component from being insoluble in the emulsion polymerisation reaction mixture. In other words, the emulsion polymerisation monomer component may be added at a suitable rate such that the monomers of the emulsion polymerisation monomer component are and/or remain substantially dissolved in the emulsion polymerisation reaction mixture. Adding the emulsion polymerisation monomer component dropwise may result in a low level of free monomer in the emulsion polymerisation reaction mixture such that the emulsion polymerisation reaction results in an emulsion polymerised acrylic latex material that displays lower agglomeration than may be expected.
- The emulsion polymerisation monomer component may be added at a variable rate during the time period for addition of the emulsion polymerisation monomer component. The emulsion polymerisation monomer component may be added at a slower rate initially and then at an increasingly faster rate during the time period for addition of the emulsion polymerisation monomer component.

For example, the emulsion polymerisation monomer component may initially be added at a rate of from 0.05 to 0.50 wt %/minute, such as from 0.1 to 0.25 wt %/minute, such as from 0.1 to 0.2 wt %/minute, or even from 0.15 to 0.2 wt %/minute based on the total solid weight of the monomers in the emulsion polymerisation monomer component for a time period from 1 minute to 3 hours, such as from 15 minutes to 2 hours, such as from 30 minutes to 90 minutes, or even for a time period of 1 hour. The emulsion polymerisation monomer component may subsequently be added at a rate of from 0.1 to 1 wt %/minute, such as from 0.2 to 0.5 wt %/minute, such as from 0.2 to 0.4 wt %/minute, or even from 0.3 to 0.4 wt %/minute based on the total solid weight of the monomers in the emulsion polymerisation monomer component for a time period from 1 minute to 3 hours, such as from 15 minutes to 2 hours, such as from 30 minutes to 90 minutes, or even for a time period of 1 hour. The emulsion polymerisation monomer component may subsequently be added at a rate of from 0.2 to 2 wt %/minute, such as from 0.4 to 1.0 wt %/minute, such as from 0.4 to 0.8 wt %/minute, or even from 0.5 to 0.8 wt %/minute based on the total solid weight of the monomers in the emulsion polymerisation monomer component for a time period from 1 minutes to 6 hours, such as from 30 minutes to 4 hours, such as from 1 hour to 3 hours, or even for a time period of 2 hours.

Derivatives of bisphenol A include, for example, bisphenol A diglycidyl ether (BADGE). The coating compositions of the present invention may also be substantially free, may be essentially free or may be completely free of bisphenol F (BPF) and derivatives thereof. Derivatives of bisphenol F include, for example, bisphenol F diglycidyl ether (BPFG). The compounds or derivatives thereof mentioned above may not be added to the composition intentionally but may be present in trace amounts because of unavoidable contamination from the environment. “Substantially free” refers to coating compositions, or components thereof, containing less than 1000 parts per million (ppm) of any of the compounds or derivatives thereof mentioned above. “Essentially free” refers to coating compositions, or components thereof, containing less than 100 ppm of any of the compounds or derivatives thereof mentioned above.

- The coating compositions may be applied to any suitable substrate. The substrate may be formed of metal, plastic, composite and/or wood. The substrate may be a metal substrate.
- The substrate may be an article such as an automotive product, a household or office appliance, furniture item or tool, a powered industrial product, a consumer electronics article, an architectural product or a product protected by an intumescent coating.
- Examples of suitable metal substrates include, but are not limited to, food and/or beverage packaging, components used to fabricate such packaging or monobloc aerosol cans and/or tubes.
- The food and/or beverage packaging may be a can, such as a metal can. Examples of cans include, but are not limited to, two-piece cans, three-piece cans and the like. Suitable examples of monobloc aerosol cans and/or tubes include, but are not limited to, deodorant and hair spray containers. Monobloc aerosol cans and/or tubes may be aluminium monobloc aerosol cans and/or tubes.
- The substrate may be a food and/or beverage packaging or component used to fabricate such packaging.
- The food and/or beverage can may comprise a can body and a can end.
- The substrate may be a monobloc aerosol can and/or tube.
- The application of various pre-treatments and coatings to packaging is well established. Such treatments and/or coatings, for example, can be used in the case of metal cans, wherein the treatment and/or coating is used to retard or inhibit corrosion, provide a decorative coating, provide ease of handling during the manufacturing process, and the like. Coatings can be applied to the interior of such cans to prevent the contents from contacting the metal of the container. Contact between the metal and a food or beverage, for example, can lead to corrosion of a metal container, which can then contaminate the food or beverage. This is particularly true when the contents of the can are acidic in nature. The coatings applied to the interior of metal cans also help prevent corrosion in the headspace of the cans, which is the area between the fill line of the product and the can lid; corrosion in the headspace is particularly problematic with food products having a high salt content. Coatings can also be applied to the exterior of metal cans.
- The coating compositions are particularly applicable for use with coiled metal stock, such as the coiled metal stock from which the ends of cans are made (“can end stock”), and end caps and closures are made (“cap/closure stock”). Since coatings designed for use on can end stock and cap/closure stock may be applied prior to the piece being cut and stamped out of the coiled metal stock, they may be flexible and extensible. For example, such stock may be coated on both sides. Thereafter, the coated metal stock is punched. For can ends, the metal is then scored for the “pop-top” opening and the pop-top ring is then attached with a pin that is separately fabricated. The end is then attached to the can body by an edge rolling process. A similar procedure is done for “easy open” can ends. For easy open can ends, a score substantially around the perimeter of the lid allows for easy opening or removing of the lid from the can, such as by means of a pull tab. For caps and closures, the cap/closure stock may be coated, such as by roll coating, and the cap or closure stamped out of the stock; it is possible, however, to coat the cap/closure after formation. Coatings for cans subjected to relatively stringent temperature and/or pressure requirements should also be resistant to popping, corrosion, blushing and/or blistering.
- The substrate may be a can end, such as a metal can end.
- The substrate may be a package coated at least in part with any of the coating compositions described herein. A “package” is anything used to contain another item, particularly for shipping from a point of manufacture to a consumer, and for subsequent storage by a consumer. A package will be therefore understood as something that is sealed so as to keep its contents free from deterioration until opened by a consumer. The manufacturer will often identify the length of time during which the food or beverage will be free from spoilage, which may range from several months to years. Thus, the present “package” is distinguished from a storage container or bakeware in which a consumer might make and/or store food; such a container would only maintain the freshness or integrity of the food item for a relatively short period of time. A package according to the present invention can be made of metal or non-metal, for example, plastic or laminate, and be in any form. An example of a suitable package is a laminate tube. Another example of a suitable package is metal can. The term “metal can” includes any type of metal can, container or any type of receptacle or portion thereof that is sealed by the food and/or beverage manufacturer to minimize or eliminate spoilage of the contents until such package is opened by the consumer. One example of a metal can is a food can; the term “food can(s)” is used herein to refer to cans, containers or any type of receptacle or portion thereof used to hold any type of food and/or beverage. The term “metal can(s)” specifically includes food cans and also specifically includes “can ends” including “E-Z open ends”, which may be stamped from can end stock and used in conjunction with the packaging of food and beverages. The term “metal cans” also specifically includes metal caps and/or closures such as bottle caps, screw top caps and lids of any size, lug caps, and the like. The metal cans can be used to hold other items as well, including, but not limited to, personal care products, bug spray, spray paint, and any other compound suitable for packaging in an aerosol can. The cans can include “two piece cans” and “three-piece cans” as well as drawn and ironed one-piece cans; such one piece cans often find application with aerosol products. Packages coated according to the present invention can also include plastic bottles, plastic tubes, laminates and flexible packaging, such as those made from PE, PP, PET and the like. Such packaging could hold, for example, food, toothpaste, personal care products and the like.
- The coating compositions can be applied to the interior and/or the exterior of the package. The coating compositions could also be applied as a rim coat to the bottom of the can. The rim coat functions to reduce friction for improved handling during the continued fabrication and/or processing of the can. The coating compositions can also be applied to caps and/or closures; such application can include, for example, a protective varnish that is applied before and/or after formation of the cap/closure and/or a pigmented enamel post applied to the cap, particularly those having a scored seam at the bottom of the cap. Decorated can stock can also be partially coated externally with the coating described herein, and the decorated, coated can stock used to form various metal cans.
- Metal coils, having wide application in many industries, are also substrates that can be coated according to the present invention. Coil coatings also may comprise a colorant.
- The coating compositions may be applied to at least a portion of the substrate. For example, when the coating compositions are applied to a food and/or beverage can, the coating compositions may be applied to at least a portion of an internal and/or external surface of said food and/or beverage can. For example, when the coating compositions are applied to a food and/or beverage can, the coating compositions may be applied to at least a portion of an internal surface of said food and/or beverage can.
- The coating composition may be applied as a repair coating for component parts of food and beverage cans. For example, as a repair coating for a full aperture easy open end for food cans. This end component may be repair coated, after fabrication, by airless spraying of the material on to the exterior of the score line. Other uses as repair coatings include the coating of seams and welds, such as side seams for which the coating may be applied to the area by spraying (airless or air driven) or roller coating. Repair coating can also include protection of vulnerable areas where corrosion may be likely due to damage, these areas include flanges, rims and bottom rims where the coating may be applied by spraying, roller coating flow or dip coating.
- An automotive product may be a vehicle or any part thereof. Any part or any surface of the vehicle which may undergo coating to improve a property thereof (for example its luster, scratch resistance, corrosion resistance or UV resistance) may be a coating with a composition as defined herein.
- The term “vehicle” is used in its broadest sense and includes (without limitation) all types of aircraft, spacecraft, watercraft, and ground vehicles. For example, a vehicle can include, aircraft such as airplanes including private aircraft, and small, medium, or large commercial passenger, freight, and military aircraft; helicopters, including private, commercial, and military helicopters; aerospace vehicles including, rockets and other spacecraft. Vehicles can include ground vehicles such as, for example, trailers, cars, trucks, buses, coaches, vans, ambulances, fire engines, motorhomes, caravans, go-karts, buggies, fork-lift trucks, sit-on lawnmowers, agricultural vehicles such as, for example, tractors and harvesters, construction vehicles such as, for example, diggers, bulldozers and cranes, golf carts, motorcycles, bicycles, trains, and railroad cars.

Any vehicular parts which may benefit from coating as defined herein may undergo coating, whether exposed to or hidden from view in normal use.
- Household and office appliances, furniture items and tools as defined herein are appliances, furniture items and tools used in the home, including the garden, or in office environments. They may include fabric washers, dishwashers, dryers, refrigerators, stoves, microwave ovens, computer equipment and printers, air conditioning units, heat pump units, lawn and garden equipment including lawn furniture, hot tubs, lawnmowers, garden tools, hedge trimmers, string trimmers (strimmers), chainsaws, garden waster shedders, garden hand tools such as, for example, spades, forks, rakes and cutting tools, cupboards, desks, table, chairs, cabinets and other articles. Any parts of any such articles which may benefit from coating as defined herein may undergo coating; for example panels of appliances or furniture and handles of tools.
- A powered industrial product may include, for example, pumps, electricity generators, air compressors, industrial heat pumps and air conditioners, batteries and cement mixers. Any parts which benefit from coating as defined herein may undergo coating; for example panels and casings.
- A consumer electronics article may be, for example, a computer, computer casing, television, cellphone, pager, camera, calculator, printer, scanner, digital decoder, clock, audio player, headphones or tablet.
- An architectural product may be, for example, a door, window, door frame, window frame, beam or support, or a panel, walling item or roofing item used in building construction, or a solar panel, a wind turbine, an oil/gas well, an off-shore rig, a storage tank, or in transportation infrastructure or utilities infrastructure.
- Products protected by intumescent coatings may be metallic structures, for example steel structures, which are coating with an intumescent coating. The metallic structures may be load bearing parts of buildings. Unprotected steel may begin to soften at around 425° C. and lose approximately half of its strength by 650° C. Intumescent coatings are employed to retard the temperature increase of the steel, or other substrate. An intumescent coating may be improved by incorporation of the defined acrylic polyester resin into the matrix of the intumescent material prior to its coating onto a metallic substrate to be protected. The acrylic polyester resin may be present in an amount of at least 1 wt %, such as at least 2 wt %, for example at least 4 wt %, or at least 5%. The acrylic polyester resin may be present in an amount of up to 50 wt % by weight, such as up to 30 wt %, for example up to 25 wt %. These definitions refer to the weight of the acrylic polyester resin by weight of the admixed acrylic polyester resin/intumescent matrix material to be applied to a substrate.
- Articles coated may fall in two or more of the categories set out above. For example computer equipment may be regarded as a household or as an office item, and as a consumer electronics item. A beam or support—an architectural item—may be coated with an intumescent material.
- In the uses defined above a coating composition may be to coat surfaces and parts thereof (except for the use in an intumescent coating which is an admixture). A part may include multiple surfaces. A part may include a portion of a larger part, assembly, or apparatus. A portion of a part may be coated with an aqueous composition or powder composition as defined herein or the entire part may be coated.
- The substrate may be new (i.e., newly constructed or fabricated) or it may be refurbished, such as, for example, in the case of refinishing or repairing a component of an automobile or aircraft.
- As mentioned above, the substrate coated may comprise a vehicle. For example, an aqueous or powder composition may be utilized in coating a F/A-18 jet or related aircraft such as the F/A-18E Super Hornet and F/A-18F (produced by McDonnell Douglas/Boeing and Northrop); in coating the Boeing 787 Dreamliner, 737, 747, 717 passenger jet aircraft, and related aircraft (produced by Boeing Commercial Airplanes); in coating the V-22 Osprey; VH-92, S-92, and related aircraft (produced by NAVAIR and Sikorsky); in coating the G650, G600, G550, G500, G450, and related aircraft (produced by Gulfstream); and in coating the A350, A320, A330, and related aircraft (produced by Airbus). An aqueous or powder composition may be used as a coating for use in any suitable commercial, military, or general aviation aircraft such as, for example, those produced by Bombardier Inc. and/or Bombardier Aerospace such as the Canadair Regional Jet (CRJ) and related aircraft; produced by Lockheed Martin such as the F-22 Raptor, the F-35 Lightning, and related aircraft; produced by Northrop Grumman such as the B-2 Spirit and related aircraft; produced by Pilatus Aircraft Ltd.; produced by Eclipse Aviation Corporation; or produced by Eclipse Aerospace (Kestrel Aircraft).
- The coating compositions may be applied to the substrate by any suitable method. Suitable methods of applying the coating compositions will be well known to a person skilled in the art. Suitable application methods for the coating compositions include, but are not limited to, the following: electrocoating, such as electrodeposition; spraying; electrostatic spraying; dipping; rolling; brushing; and the like.
- The coating compositions may be applied to the substrate, or a portion thereof, as a single layer or as part of a multi-layer system. The coating compositions may be applied as a single layer. The coating compositions may be applied to an uncoated substrate. For the avoidance of doubt, an uncoated substrate extends to a surface that is cleaned prior to application. The coating compositions may be applied on top of another paint layer as part of a multi-layer system. For example, the coating compositions may be applied on top of a primer. The coating compositions may form an intermediate layer or a top coat layer. The coating compositions may be applied as the first coat of a multi coat system. The coating compositions may be applied as an undercoat or a primer. The second, third, fourth etc. coats may comprise any suitable paint such as those containing, for example, epoxy resins; polyester resins; polyurethane resins; polysiloxane resins; hydrocarbon resins or combinations thereof. The second, third, fourth etc. coats may comprise polyester resins. The second, third, fourth etc. coats may be a liquid coating or a powder coating.
- It will be appreciated by a person skilled in the art that the coating compositions may be applied before or after forming the article, such as the packaging. For example, the coating compositions may be applied to metal substrate which is then shaped and formed into a metal article, or the coating composition may be applied to the preformed article.
- The coating compositions may be applied to a substrate once or multiple times.
- The coating compositions may be applied to the substrate by any suitable method. Methods of applying the coating compositions will be well known to a person skilled in the art. Suitable application methods for the coating compositions include, but are not limited to, the following: electrocoating; spraying; electrostatic spraying; dipping; rolling; brushing; and the like.
- Further information about suitable application methods of applying suitable coating compositions to substrates will now be given.
- A liquid coating composition may be electrophoretically deposited upon any electrically conductive substrate. Suitable substrates include metal substrates, metal alloy substrates, and/or substrates that have been metallized, such as nickel-plated plastic. Additionally, substrates may comprise non-metal conductive materials including composite materials such as, for example, materials comprising carbon fibers or conductive carbon. The metal or metal alloy may comprise, for example, cold rolled steel, hot rolled steel, steel coated with zinc metal, zinc compounds, or zinc alloys, such as electrogalvanized steel, hot-dipped galvanized steel, galvannealed steel, nickel-plated steel, and steel plated with zinc alloy. The substrate may comprise an aluminum alloy. Non-limiting examples of aluminum alloys include the 1XXX, 2XXX, 3XXX, 4XXX, 5XXX, 6XXX, or 7XXX series as well as clad aluminum alloys and cast aluminum alloys, such as, for example, the A356 series. The substrate may comprise a magnesium alloy. Non-limiting examples of magnesium alloys of the AZ31B, AZ91C, AM60B, or EV31A series also may be used as the substrate. The substrate may also comprise other suitable non-ferrous metals such as titanium or copper, as well as alloys of these materials.
- The part to be coated may be in the shape of a cylinder, such as a pipe, including, for example, a cast iron or steel pipe. The metal substrate also may be in the form of, for example, a sheet of metal or a fabricated part. The substrate may also comprise conductive or non-conductive substrates at least partially coated with a conductive coating. The conductive coating may comprise a conductive agent such as, for example, graphene, conductive carbon black, conductive polymers, or conductive additives. It will also be understood that the substrate may be pretreated with a pretreatment solution. Non-limiting examples of a pretreatment solution include a zinc phosphate pretreatment solution such as, for example, those described in U.S. Pat. Nos. 4,793,867 and 5,588,989, a zirconium containing pretreatment solution such as, for example, those described in U.S. Pat. Nos. 7,749,368 and 8,673,091. Other non-limiting examples of a pretreatment solution include those comprising trivalent chromium, hexavalent chromium, lithium salts, permanganate, rare earth metals, such as yttrium, or lanthanides, such as cerium. Another non-limiting example of a suitable surface pretreatment solution is a sol-gel, such as those comprising alkoxy-silanes, alkoxy-zirconates, and/or alkoxy-titanates. Alternatively, the substrate may be a non-pretreated substrate, such as a bare substrate, that is not pretreated by a pretreatment solution.
- The substrate may optionally be subjected to other treatments prior to coating. For example, the substrate may be cleaned, cleaned and deoxidized, anodized, acid pickled, plasma treated, laser treated, or ion vapor deposition (IVD) treated. These optional treatments may be used on their own or in combination with a pretreatment solution.
- A liquid composition may be utilized in an electrocoating layer that is part of a multi-layer coating composite comprising a substrate with various coating layers. The coating layers may optionally include a pretreatment layer, such as a phosphate layer (e.g., zinc phosphate layer) or metal oxide layer (e.g., zirconium oxide layer), an electrocoating layer which results from an aqueous composition, optionally primer layer(s) and suitable topcoat layer(s) (e.g., base coat, clear coat layer, pigmented monocoat, and color-plus-clear composite compositions). It is understood that suitable additional coating layers include any of those known in the art, and each independently may be waterborne, solvent-borne, in solid particulate form (i.e., a powder coating composition), or in the form of a powder slurry. The additional coating compositions may comprise a film-forming polymer, crosslinking material and, if a colored base coat or monocoat, pigment. The primer layer(s) may optionally be disposed between the electrocoating layer and the topcoat layer(s). Alternatively, the topcoat layer(s) may be omitted such that the composite comprises the electrocoating layer and primer layer(s).
- Moreover, the topcoat layer(s) may be applied directly onto the electrodepositable coating layer. In other words, the substrate may lack a primer layer such that the composite comprises the electrocoating layer and topcoat layer(s). For example, a basecoat layer may be applied directly onto at least a portion of the electrodepositable coating layer.
- It will also be understood that any of the topcoat layers may be applied onto an underlying layer, despite the fact that the underlying layer has not been fully cured. For example, a clearcoat layer may be applied onto a basecoat layer even though the basecoat layer has not been subjected to a curing step (wet-on-wet). Both layers may then be cured during a subsequent curing step thereby eliminating the need to cure the basecoat layer and the clearcoat layer separately.
- “Powder” and like terms, as used herein, refers to materials that are in the form of solid particulates, as opposed to materials which are in the liquid form.
- Powder coating compositions may be applied by any suitable method. Methods of applying said powder coating compositions will be well known to a person skilled in the art. Suitable application methods include, such as electrodeposition, or applied by ultra corona discharge for example. The powder coating compositions may be applied by ultra corona discharge.
- When the substrate is electrically conductive, the powder coating composition may be electrostatically applied. Electrodeposition generally involves drawing the coating composition from a fluidized bed and propelling it through a corona field. The particles of the coating composition become charged as they pass through the corona field and are attracted to and deposited upon the electrically conductive substrate, which is grounded. As the charged particles begin to build up, the substrate becomes insulated, thus limiting further particle deposition.
- The coating compositions may be in the form of a liquid or a powder.
- The coating compositions may be in the form of a liquid. The coating compositions may be solvent-borne or aqueous.
- The coating compositions may be applied to the substrate by spraying. Thus, the coating compositions may be spray compositions. For the avoidance of doubt, by the term ‘spray composition’ and like terms as used herein is meant, unless specified otherwise, that the coating is suitable to be applied to a substrate by spraying, i.e. is sprayable.
- The coating compositions may be applied to any suitable dry film thickness. The coating compositions may be applied to a dry film thickness from 1 to 100 microns (μm), such as from 1 to 75 μm, such as from 1 to 50 μm, such as from 1 to 40 μm, such as from 1 to 20 μm, or even from 1 to 10 μm.
- The coating compositions and/or layers deposited from the same, as well as any pretreatment layer, primer layer or topcoat layer, may be substantially free of chromium or chromium-containing compounds meaning that chromium or chromium-containing compounds are not intentionally added, but may be present in trace amounts, such as because of impurities or unavoidable contamination from the environment. In other words, the amount of material is so small that it does not affect the properties of the composition; this may further include that chromium or chromium-containing compounds are not present in an aqueous or powder composition and/or layers deposited from the same, as well as any pretreatment layer, primer layer or topcoat layer, in such a level that they cause a burden on the environment. The term “substantially free” means that a coating composition and/or layers deposited from the same, as well as any pretreatment layer, primer layer or topcoat layer, contain less than 10 ppm of chromium, based on total solids weight of the composition, the layer, or the layers, respectively, if any at all. The term “essentially free” means that a coating composition and/or layers deposited from the same, as well as any pretreatment layer, primer layer or topcoat layer, contain less than 1 ppm of chromium, based on total solids weight of the composition or the layer, or layers, respectively, if any at all. The term “completely free” means that a coating composition and/or layers comprising the same, as well as any pretreatment layer, primer layer or topcoat layer, contain less than 1 ppb of chromium, based on total solids weight of the composition, the layer, or the layers, respectively, if any at all.
- The coating compositions may be cured by any suitable method. The coating composition may be cured by heat curing, radiation curing or by chemical curing, such as by heat curing.
- The coating composition, when heat cured, may be cured at any suitable temperature. The coating composition, when heat cured, may be cured to a peak metal temperature (PMT) of 100° C. to 350° C., such as 150° C. to 350° C., such as from 175° C. to 320° C., such as from 190° C. to 300° C., or even from 200° C. to 280° C. For the avoidance of doubt, the term “peak metal temperature”, and like terms as used herein, is meant unless specified otherwise the maximum temperature reached by the metal substrate during exposure to a heat during the heat curing process. In other words, the peak metal temperature (PMT) is the maximum temperature reached by the metal substrate and not the temperature which is applied thereto. It will be appreciated by a person skilled in the art that the temperature reached by the metal substrate may be lower than the temperature which is applied thereto or may be substantially equal to the temperature which is applied thereto. The temperature reached by the metal substrate may be lower than the temperature which is applied thereto.
- Curing the coating compositions may form a cured film.
- The ester, amide and/or thioester of the cyclic unsaturated acid anhydride and/or diacid derivative thereof may form an acid anhydride group at an elevated temperature, such as above 100° C., for example during curing, by removal of an alcohol, amine and/or thiol. The acid anhydride group formed may then be reacted with a hydroxyl group to form a carboxyl group.
- The diacid derivative of the cyclic unsaturated acid anhydride may form an acid anhydride group at an elevated temperature, such as above 100° C., for example during curing, by removal of water. The acid anhydride group formed may then be reacted with a hydroxyl group to form a carboxyl group.

- Synthesis of a homopolymer of maleic acid: 240 grams (g) xylene and 240 g maleic anhydride were added to a four neck round bottom flask equipped with a mechanical stir blade, thermocouple and reflux condenser. The mixture was heated to a set point of 60° C. under a nitrogen atmosphere. Once the maleic anhydride was dissolved, 1.2 g of octylamine was added and the mixture was held for 5 minutes. Next, the mixture was heated to 140° C. set point. At 140° C. a solution of 200.4 g xylene and 24 g di-tertiary butyl peroxide was added over a time period of two hours via an addition funnel. After the addition was complete, the resin mixture was then held at 140° C. for two hours. Next, the mixture was cooled to 110° C. to prepare the solution for vacuum distillation. At 110° C. the xylene solvent was removed by vacuum distillation to obtain 263.9 g of distillate. After 2 hours, the distillation process was stopped and 131.4 g of deionized water was added over 60 minutes. After this addition, the reactor was set up with a Dean-Stark apparatus to remove residual xylene. After 1 hour, 306.6 g of deionized water was added over 60 min and the reaction was held at 110° C. for 15 min.

The results are shown in Table 3.
- Test panel preparation: the coatings were drawn down onto flat aluminium cans using either a #14 or a #16 wire bar in order to achieve target film weights in the 5 to 6 g/m2 range. The coatings were baked in a box oven set at 215° C. for one minute and forty-five seconds (1 min 45 s). The dry film weights were determined using a SENCON S19600 Coating Thickness Gauge.
- Corrosion resistance: a first set of coated substrates were exposed to boiling (100° C.) 5% acetic acid for 30 minutes in an 800 mL beaker on a temperature-controlled CORNING PC-420D hot plate. A second set of coated substrates were exposed to boiling (100° C.) 3% acetic acid for 30 minutes in an 800 mL beaker on a temperature-controlled CORNING PC-420D hot plate. A third set of coated substrates were exposed to boiling 3% acetic acid for 30 minutes in an 800 mL beaker on a temperature-controlled CORNING PC-420D hot plate followed by storage for ten days in 3% acetic acid in a sealed container at 40° C. A fourth set of coated substrates were exposed to a 1% Joy® detergent solution for 10 minutes at 82° C. on a temperature-controlled CORNING PC-420D hot plate. The coated substrates were then tested for blistering and adhesion as follows.
- Blistering: blistering was determined according to ASTM D714 (“Standard Test Method for Evaluating Degree of Blistering of Paints”), which contains photographic reference standards for the degree of blistering.
- Adhesion: The panels were tested for coating adhesion to the substrate using the BYK Cross-Cut Tester Kit #5127 with a 1.5 mm blade according to the manufacturer's instructions. The results were assessed visually and rated from 0 to 5, with 0 meaning no loss of adhesion, 1 meaning <5% loss of adhesion, 2 meaning a 5% to 15% loss of adhesion, 3 meaning a 16% to 35% loss of adhesion, 4 meaning a 36% to 65% loss of adhesion and 5 meaning an >65% loss of adhesion. The loss percentage was assessed in the area of the scribe.
- MEK double rubs: MEK resistance was determined using a two pound ball hammer using MEK soaked gauze covering the ball end of the hammer. The number of double rubs until the coating failed to the substrate was recorded.
- Flexibility: the coating compositions were drawn down on tinplate substrate for flexibility testing using an BYK Gardner Impact Tester to apply a 48 inch-lbs impact force to the coated and folded tinplate panels. The coated panels were then rusted by exposure to a solution of 15% copper sulphate and 7.5% hydrochloric acid in deionised water for two minutes. After this time, the amount of rust-free length was recorded (the total tinplate length being 100 mm). The length in millimetres (mm) of the coated panel that is free from continuous rusting and spotted or peppering rusting was recorded.
