Description
FAST FILM FORMING WATER BASED BARRIER COATING
TECHNICAL FIELD
The present invention relates to a novel composition that allows for the formation of a continuous and cohesive film which provides water resistance, grease and oil resistance release, water repellency, water vapour resistance at a very fast set speed without the need of a thermal energy, to be used as wax replacement treatment and a top coat for flexible packaging. The invention also relates to packaging, containers, food wrappers, receptacles and the like formed from such coated materials. The invention also relates to methods for making same. The invention also relates to surface treatments in which the surface is for example metal, textile, wood, concrete and related building products.
BACKGROUND ART
Water based barrier coatings when applied to paper and paperboard contain water that has to be removed to form a continuous film. The quality of the continuous film, free of defects, is very important to achieve the optimal barrier properties.
A drying process normally removes water. The drying process is usually a thermal one (conduction, convection, radiation) in which heat is provided to the liquid to vaporize the water.
The drying condition is one of the most important factors that affect the coating performance. Quality problems such as bubbles, blisters, pinholes or cracks can occur with improper drying conditions. The production conditions must be adapted to the type of machine, coating used and the coat weight.
The cost of the drying represents a major part of the process cost, and as energy costs rise, drying efficiency becomes increasingly important.

DESCRIPTION OF PREFERRED EMBODIMENTS
The present invention relates to a water based wax-free coating which forms a film at a very fast rate without the need for added heat. It provides excellent water resistance (tack free), grease and oil resistance and good water vapour barrier properties.
The success of functional coatings generally depends on having a uniform coating. A
continuous film, free of defect, is particularly important for barrier properties. Film formation in coating involves the change from liquid to solid state. This is done by the evaporation of the water and coalescence of the particles of the dispersion.
The polymer is initially present as discrete spheres separated by a continuous water phase.
The water is removed by evaporation and by penetration into the porous substrate. As the concentration increases, the polymer particles move closer together. In this particular case, water is absorbed so fast by the substrate, that the spheres or particles are forced into ever-closer contact.
Eventually, the spheres become crowded so tightly, that the space between them creates capillary forces. As close packing occurs, the capillary force of the water draws the spheres or particles together to form a continuous and cohesive film.

The ease of film formation depends on the glass transition temperature, commonly known as Tg, of the polymer, the particle size, the formulation ingredients and the temperature reached during the drying process.

A NDED SHEET
The ease of film formation depends on the glass transition temperature, commonly known as Tg, of the polymer, the particle size, the formulation ingredients and the temperature reached during the drying process.
The present invention relates to an entirely different process wherein a salt such as calcium stearate influences the rate of film formation. Salts such as calcium stearate act as a coalescent agent by reducing the minimum film forming temperature. Also, the salt, such as calcium stearate acts as an emulsifier and reduces the surface tension of the mixture; this allows the coating to wet the surface thoroughly and the water present in the coating is rapidly removed by penetration into the porous paper substrate.
The presence of the fatty acid complex of a metal ion, such as chromium, enhances the rate of the film formation at the same time helping to get a better film property including release, water repellency, water, water vapour, grease and oil resistance.
Therefore the water based barrier coating of the present invention rapidly forms a continuous and cohesive film free of defects, without the need for heat. The fast set drying film formation concept of this novel water based barrier coating composition allows barrier coating technology to extend the application to the non conventional equipment such as size press coaters, spray coaters, curtain coaters and flexo where thermal sources are deficient or absent.
The term catalytic composition herein is intended to mean a pre-mixture of i) a salt of one or more of myristic, palmitic and stearic acid; ii) a C9-C18 fatty acid complex of a metal ion, said metal ion having an oxidation state of at least 3.
The term polymeric film-forming composition herein is intended to mean a composition comprising i) a salt of one or more of myristic, palmitic and stearic acid;
ii) a C9-C18 fatty acid complex of a metal ion, said metal ion having an oxidation state of at least 3; and iii) a polymeric composition comprising a polymer, copolymer, or a mixture of polymers or AMEMED SHEET

The present invention relates to a novel composition that allows for the formation of a continuous and cohesive film which provides water resistance, grease and oil resistance, and water vapour barrier properties at a very fast set speed without the need of a thermal energy and which can be used as wax replacement treatment and a top coat for flexible packaging.
The absence of the need to apply thermal energy has dramatic advantages from an industrial, commercial, plant manufacturing and economic stand point. The ability to provide a continuous and cohesive film which provide a water resistance, grease and oil resistance, and water vapour barrier properties without the presence of wax has dramatic environmental implications, as well as economic considerations given the volatile costs of petroleum based products.
The term absence of thermal energy, or the need for added thermal energy is intended to mean that a heater, oven or other direct heating device is not required in the film-forming process of the-invention. The process occurs without direct heating. Otherwise stated, the film-forming process occurs at a temperature from about 0 to 50 C, typically from about 10 to 45 C, such as 15 to 40 C, typically at ambient temperature between 15 to 35 C.
The catalytic composition allows for the water-based polymeric composition to form a film at a first rate without added heat. The catalytic composition allows for the water-based polymeric composition to form a film without added heat with the film-formation in less than one minute from application of the composition to the surface. The catalytic composition allows for the water-based polymeric composition to form a film without added heat and without the use of wax. The terms wax free composition, free of wax, without wax is intended to mean a polymeric composition, and resultant film with less than 0.1% wax, typically with 0% wax.
The film-forming polymeric composition of the invention may optionally comprise a tackifier resin, such as an aqueous dispersion of glycerol ester of hydrogenated rosin.
The film-forming polymeric composition of the invention may optionally comprise a filler selected from the group consisting of delaminated clays, kaolin, mica, talc or a mixture, silicate, calcium silicate, calcium carbonate, aluminium hydrate, and mixtures thereof.
The film-forming polymeric composition of the invention may optionally comprise a dispersing agent, a thickener agent, a defoaming agent, a slip agent, an antiskid agent, rheology modifiers, pigments, susceptor materials, crosslinking agents, catalysts, flame retardants, biocides, and wetting agent.
Pigment may be added to the film-forming composition to give the surface of the coated substrate or sheet material a desired appearance. For example, it may be desired that a food-contacting surface of the coated sheet material be a white color. In the event brown kraft paper is used as the substrate sheet material, titanium dioxide may be added to the barrier coating composition to make it white and to make the food-contacting surface of the sheet material white when the barrier coating composition is applied. Pigments such as TI-PURE
900, a titanium dioxide pigment made by DuPont, are suitable pigments for the barrier coating. Other pigments or dispersions may be suitable so long as they do not significantly degrade the performance of the barrier coating composition.
A dispersing agent may be added to the film-forming composition to help disperse and suspend any component, including fillers and pigment particles, in the composition before application, and to stabilize the suspension. Any of a variety of dispersing agents may be used. For example, dispersing agents such as tetra sodium pyrophosphate ("TSPP") and sodium hexa meta phosphate are suitable for this purpose. It may be desirable to add a minor amount of fine metal powder or flakes, such as aluminum powder or flakes, to the barrier coating composition or release coating composition as a susceptor material.
The fast drying film formation barrier coatings composition suitably comprises, in weight %
to a total of 100%, the following:
- Stearate calcium, aluminium or zinc dispersion: 5 to 30%, preferably 17 to 27%
