The method is generally applicable to hard surfaces with, at times, minor modifications. These minor modifications are within the level of skill in the art and are typically not described herein in detail.
  • Several illustrative examples for applying the nontoxic surface coatings of the present invention are provided below in the Example.
  • Coating compositions of the present invention may be used direct to substrate unless working on bare metal. When painting bare metal apply a urethane primer or sealer to serve as a corrosion barrier. b) Sand off primers on after-market parts prior to painting. c) Use an adhesion promoter prior to painting plastics & oily surfaces. d) Coating compositions of the present invention are compatible with all urethane and waterborne primers. Start with intial coat(s) of 4000 Base Coat Sealers. Use of Base Coat Sealers may be omitted when using underlying finish for color key purposes. For best atomization, spraygun should be 12-15" away from the surface. Apply all coats very lightly.
  • Coating compositions of the present invention should be applied as light acclimation/ guide coats.
  • Initial coats have a speckled appearance. Additional coats fill in coverage producing an even finish. Apply color in dry coats. Avoid applying colors in wet coats. Wetted coats may cause pigment to migrate causing a "fish-eye" effect. Color blending and spot repairs are best done when the underlying coat has dried. Colors dry to a dull matte finish with a rough porous texture. Many of the special effect colors are are not fully visible until after clear coat is applied.
  • An Infra-red (LR) lamp is recommended when painting a full vehicle.
  • a heat gun is effective when curing smaller areas such as body panels, tanks, fenders, helmets, etc. Keep heat gun moving to aviod blistering.
  • Surface temperature 120-140°F best.
  • Cure time depends greatly on painting enviroment (temperature & humidity) and thickness/build height of paint coats.
  • An average cure time using convection heat for 1 square foot is 2-3 minutes. Use of infra red heat may reduce cure time up to 50%.
  • Coating compositions of the present invention are compatible with all urethane and waterborne primers.
  • Base Coat Sealers may be omitted when using underlying finish for color key purposes.
  • spray gun should be 12-15" away from the surface. Apply all coats very lightly. Coats should be applied as light acclimation/guide coats. Initial coats have a speckled appearance. Additional coats fill in coverage producing an even finish.
  • Coating compositions of the present invention can be base coat graphic paints for custom automotive painting and are non-toxic, containing less than 0.10% VOC. Coating compositions of the present invention consist of two essential components; binder and pigment. The binder is an advanced water based, non-toxic polymer designed specifically for automotive or other like applications.
  • the pigments used can be automotive pigments, the same used by the actual vehicle manufacturer.
  • Coating compositions of the present invention can be used as the base coat for an entire paintjob, which is then coated with a finishing clear; Coating compositions of the present invention may also be used for graphics applied into a sanded and prepared urethane or polyurethane finish then coated with a clear. Coating compositions of the present invention are designed to he coated with a clear coat finish for maximum permanence. Coating compositions of the present invention work excellent with virtually all urethane or polyurethane clear coats of any grade. There are no compatibility issues between paint and clear coat when working with Coating compositions ofthe present invention .
  • Coating compositions ofthe present invention Due to the Coating compositions ofthe present invention's porosity, the clear coat is absorbed directly into the paint creating a strong, uniform bond. The result is perfect unison between the base colors and clear coat. Coating compositions ofthe present invention have a "death grip" on the clear coat. They will generally not lift or peel. Coating compositions ofthe present invention have greater flexibility than urethane and lacquer base coat paints, making them more resistant to chipping and flaking. When spraying on fiberglass, Auto Air Color do not create an electro-static charge as do urethane base coats which makes dust and debris stick to the color.
  • Sanding and/or scuffing needs to completely remove any gloss points from the surface. Close attention needs to be made with crevices, edges, folds and other areas difficult to sand with broad strokes. Peeling often occurs in such areas where sanding does not thoroughly scuff.
  • the grade of sandpaper, method and application technique may vary. Choosing between a coarse scuff pad, using a sandpaper block, or dual-action sander is a matter of choice and accessibility. What is important is to make sure the entire surface is removed of gloss points and that the surface is roughed up so that that the coating compositions ofthe present invention may "grip" onto the surface. After sanding, clean the surface once again with a solvent-based degreaser.
  • Coating compositions ofthe present invention are compatible with all urethane and epoxy automotive primers. However, use of such primers is often not required when using Coating compositions ofthe present invention . The following is a list of when to use a primer when painting with Coating compositions ofthe present invention . This list does not cover body- fill issues and when to use high-build primers.
  • Metal - use a urethane or waterborne primer or sealer as a corrosion barrier between exposed metal and Coating compositions ofthe present invention . Water-based paint embodiments will corrode metal when direct contact is made.
  • Plastics use of an adhesion promoter or mid-coat clear is recommended when painting plastics in addition to thorough sanding. Although Coating compositions ofthe present invention adhere to plastics, peeling is possible when taping. Plastics can have an oily texture with which water-based paints have difficulty adhering. Use of an adhesion promoting mid-coat clear prevents the possibility of peeling.
  • Urethane finishes Coating compositions ofthe present invention do not require a primer when painting direct to an existing urethane finish after sanding, such as when applying graphics to a factory paintjob. However, if the finish is in poor condition, sanding and use of a primer is recommended to create an even finish. If metal is exposed when sanding a finish, apply a urethane sealer to the area exposed to prevent corrosion. In such an instance, a spray can urethane sealer works well for small areas.
  • Aluminum Coating compositions ofthe present invention adhere well to bare aluminum. Use of a primer is not required. Fiberglass - Coating compositions ofthe present invention adhere well to fiberglass. Use of a primer is not required.
  • Carbon-fiber - Coating compositions ofthe present invention adhere well to carbon- fiber. Use of a primer is not required. After-market body kits & parts - Remove or thoroughly sand the primer on aftermarket body pieces when painting aftermarket body parts, hoods, etc., attention to detail during preparation is essential. The primer must be either removed or thoroughly sanded/ scuffed. Sanding with 320-grit paper is recommended. The primer on the aftermarket parts often has silicone type products in it that help protect the part during shipping and storage. Coating compositions ofthe present invention will not hold onto such primers without thorough sanding or scuffing.
  • an adhesion promoter on Plastic Body Parts
  • an adhesion promoter is recommended, especially on older parts.
  • coating compositions ofthe present invention adhere to plastics after scuffing, older parts that have been treated with cleaning and glossy/shining agents may create adhesion difficulties.
  • Such agents contain waxes or silicates which become imbedded in the plastic and may not allow proper adhesion ofthe paint to the plastic.
  • Use of an adhesion promoter on the plastic prior to painting with the Coating compositions ofthe present invention will prevent any adhesion difficulties gloss creating shines may create.
  • Coating compositions of the present invention must be thoroughly shaken prior to use. Coating compositions ofthe present invention have a high pigment load in a low viscosity binder. Settling ofthe pigment is intended. Coating compositions ofthe present invention must be thoroughly shaken prior to use. Coating compositions ofthe present invention may need to be placed upside down for a few minutes to loosen up settled particles after extended shelf storage. Coating compositions ofthe present invention are best used under warm, dry and dust free conditions. The inventors recommend using the coating compositions ofthe present invention under shop conditions with a minimum temperature of 70° F. Coating compositions ofthe present invention are water-based and lose excess water through evaporation as they cure. Cold and damp conditions inhibit evaporation and will retard the curing process.
  • Coating compositions of the present invention are not recommended for use in conditions below 50° F.
  • a heat lamp or other heat source to warm and dry coating compositions ofthe present invention is essential.
  • Coating compositions ofthe present invention must be thoroughly dry prior to clear coating. The more humid or colder the environment, the more the drying time will be slowed, hi especially humid conditions, the use of a heat gun or lamp is strongly recommended to speed up the drying time and ensure all the excess water is evaporated from the paint. Also, in a humid environment, even after the colors have dried, the porous nature ofthe colors will allow moisture to build on the colors.
  • the coating compositions of the present invention have a strong bond to the surface they are applied to and work well with high tack masking film. Re-exposing the colors to heat prior to masking or clearing in a humid environment is also a good idea to ensure there is no vapor lock. To ensure colors are free of contaminants, pass coating compositions of the present invention through a filter prior to spraying. A number of filtration steps are used to ensure the colors are free of contaminants. However, small bits of hardened paint may form once the caps on the coating compositions of the present invention bottles have been opened and the colors are exposed to fresh air.
  • a light coat of coating compositions ofthe present invention should look dry.
  • a medium- wet coat looks wetted as the individual color particles link up to create a continuous film. 2-3 dry light passes often is what it takes to create a wetted coat.
  • Airbrushing Thinning with Auto Air Reducer Thinning Coating compositions ofthe present invention is often necessary when airbrushing certain color series, such as: 4100 Series Aluminum Bases 4200 Series Semi-Opaque Colors 4300 Series Colors There is no exact ratio of Reducer required. Add as much needed to allow colors to flow given airbrush's particular size and operation/psi settings. Reducer may be as much 25-50%) volume of mixture or more.
  • Sanding Coating compositions ofthe present invention sand better with a coarser grades of paper, 500 to 800 grit dry. Do not wet sand Coating compositions ofthe present invention . Colors sandable after thoroughly cured. Best results 12 to 24 hours after curing.
  • Coating compositions of the present invention can be cured in a spray booth with air movement, by infrared heat lamps or with a heat gun. Curing paint is most important prior to clearing or taping/ masking. Heat Lamps (Short Wave Infrared Lamps) are recommended for working with the coating compositions ofthe present invention . Infrared Lamps will thoroughly dry and cure the paint in a short amount of time. Using Infrared Lamps also eliminates the extended drying time and surface tack that humid conditions may create. Although heat guns work well, a heat lamp is easier to work with, covers a larger area and ensures that the colors are thoroughly cured. Coating compositions ofthe present invention may also be cured by warm moving air from a source over the surface ofthe paint.
  • cross-linking is similar to a urethane catalyzing.
  • the application of heat to the colors when they are drying or soon after they have dried creates a reaction inside the colors in which the individual acrylic polymer strands link up with one another ("crosslink") to create a strong, uniform mesh.
  • the heat source may be a hot air gun, heated/infrared lamp, heated spray booth, etc.
  • the heat curing process is recommended, but not always necessary. We recommend that the colors be cured with heat prior to masking or clear coating. Simply exposing the colors to heat for a short duration while they are drying or soon after they have dried will work.
  • the heat does not have to be excessive. Heating the colors so that they are warm and dry to the touch will work well. Drying time depends, but for a square foot area dried with a heat gun, heat curing time should be around a half minute. Curing coating compositions of the present invention in humid or cold damp conditions requires extended exposure to heat. Coating compositions ofthe present invention are water-based and as such, evaporate excess water when they cure. Cold and humid conditions inhibit the evaporation ofthe excess water, which retards the curing process. To counter this, coating compositions ofthe present invention should be exposed to heat from a hot air gun or heat lamp for an extended period of time. Cure colors prior to sanding and masking. When applied in light coats and cured, colors will not lift.
  • Coating compositions ofthe present invention are compatible and work excellent with all urethane and polyurethane clear coats of any grade.
  • the secret to the coating compositions ofthe present invention superior compatibility with clear coats is its porosity. Clears are absorbed into the Coating compositions ofthe present invention creating a strong, uniform bond. There is no lifting or peeling and the results are long lasting. Coating compositions ofthe present invention do not have to be sanded prior to clear coating.
  • Base Coat Sealers 4000 Series Sealers - Additives - Cleaners Coat Sealer White or Dark Auto Air Base Coat Sealer White and Dark are a low build, adhesive sealer coat. Base Coat Sealers have higher adhesion properties. They cover well making them ideal for use as an initial coat. 4000 Base Coat Sealers are best used with a large airbrush or a spray gun. Base Coat
  • Base Coat Sealers may need thinning with Reducer if the airbrush is small or if air pressure is less than 40psi when using less than a 1.0mm size tip. Use ofthe Base Coat Sealers is not always necessary. When Coating compositions of the present invention are used over an underlying finish, use of Base Coat Sealers may be omitted when color keying with finish's color is desired. Once surface has been prepared, apply either Base Coat Sealer over the entire surface. Base Coat Sealer White and Dark can be used to remove small, minor surface imperfections to create a uniform, even surface for base coat color application. Product works best when sprayed on in light layers. 1 or 2 coats should be, applied, although 1 coat will often be enough as the Base Coat Sealer is opaque and covers well.
  • Base Coat Sealers should be cured with heat before applying additional coats. When applied as directed in lightly layered coats, curing time should be quick.
  • Base Coat Sealer Dark should be used as an adhesive primer under most coating compositions ofthe present invention.
  • Base Coat Sealer Dark is a very black-like grey shade that can be used as a black undercoat to enhance the effects of other colors. Should not replace use of a black or white color.
  • Base Coat Sealer White can be use as an adhesive primer for under lighter colored base colors to allow for more luminescent, brilliant colors.
  • Auto Air Reducer- Thinner Reducer is used to thin coating compositions ofthe present invention. Using Reducer to thin the colors will improve the atomization of some of the heavier pigmented colors, such as the 4300 Series.

They are highly reflective which allows for a lot of light to be redirected back through the Candy Colors. 1st - One Coat Base Coat Sealer Dark (when working with the Aluminum bases, an undercoat of a Base Coat Sealer needs to be applied for its adhesion). 2nd - Aluminum Base, 2-3 coats until a good coverage is achieved.
  • Hot Rod Sparkle White 1 or 2 light dust coatings. Just enough to create some pearlesence on the Aluminum Base but not enough to totally cover it. Light needs to be able to pass through this coat(s) and hit the Aluminum Base and be reflected back.
  • the Hot Rod Sparkle White may be replaced with 4301 Pearl White, 4330 Metallic White (fine) or 4331 Metallic White (coarse).
  • 4th - Candy Color 3-6 coats. The Candy Colors have a thin viscosity and must be applied lightly. Several light coats need to be applied. Allow the Candys to air dry or cure with heat in between coats. Heat curing may be better as it will heat the surface for the next coat of Candy Color.
  • 5th - Clear Other colors from the 4300 and 4500 Series may be used as the base for the Candy Colors as well. Color keying the base to match or compliment the Candy creates beautiful finishes. For example, Hot Rod Sparkle Gold or Metallic Gold used as a base for a Yellow or Sunset Candy creates a Gold Candy.
  • Metallic Colors Base for Transparent Colors 4300 Series Metallic Colors are excellent for use as undercoats for the 4200 Series Transparent Colors for custom metallic creations. Color keying the metallic base to the overlying transparent color creates vibrant, shimmering colors that reflect well in direct light and sunlight.
