The invention relates to colorant compositions, and aqueous latex paints or other water-borne coatings made from them, which have a mitigated environmental impact. Levels of solvents, additives and impurities comprising volatile non-aqueous constituents, alkylphenol ethoxylates (and derivatives thereof), crystalline silica, and/or formaldehyde are decreased relative to those typical of preceding generations of colorants and tinted aqueous latex paints and other water-borne coatings. On the other hand, paint-performance as indicated by any of Stormer viscosity stabilization, rheological profile flow/leveling and sag resistance, water sensitivity and color transfer resistance is comparable to a paint in which the aforementioned solvents, additives and impurities are still present.

An emulsion-based latex aerosol paint comprises 5-50 weight percent of one or more hydrocarbon solvents, 0.05-10 weight percent of a surfactants with a Hydrophilic-Lipophilic Balance value of 4-10, 10-70 weight percent of a water-based coating emulsified into a mixture of the one or more solvents and the one or more surfactants. The emulsion-based latex aerosol paint may be additionally charged with a hydrocarbon propellant at a level of 5 to 50 weight percent. The hydrocarbon propellant may be selected from propane, butane, isobutene and mixtures thereof. A method of making an emulsion-based latex aerosol paint comprises providing one or more aliphatic solvents, adding one or more surfactants to the one or more aliphatic solvents to provide a solvent/surfactant mixture, adding a water-based coating to the solvent/surfactant mixture and emulsifying the water based coating in the solvent surfactant mixture to provide a water-based coating emulsion, and placing the water-based coating emulsion in a delivery system utilizing a hydrocarbon propellant.

Water-based stains are based on an oil-in-water emulsion having a binder that includes, consists of, or consists essentially of drying oil combined with a non-aqueous polymer dispersion. The compositions can be tinted using traditional water-based pigment dispersions, yet the overall hydrophobicity results in minimal interaction with the polar cellulosic structure of wood.

The present invention relates to an emeraldine base composite, its preparation, and use as an effective anticorrosive pigment additive for corrosion inhibition. The emeraldine base composite comprises an insulating form of polyaniline or its derivatives adhered to an inorganic or organic material substrate such that the emeraldine base covers from about 1-100% surface of the material. Inter alia, the emeraldine base composite can be added to a coating as an anticorrosive pigment additive that inhibits corrosion and as a filler material that increases strength and barrier properties of coating.

This invention describes a dispersion for coating a polymer surface comprising polyglycerol esters and a surfactant being a neutralized or partially neutralised fatty acid or a neutralized or partially neutralized ester of fatty acids. The dispersion can be diluted into a coating composition, which can be applied as a coating on a polymer surface. The coating has anti-static and anti-fogging effects and can be used for for example a variety of different packaging materials.

A coating composition is prepared from an aqueous dispersion of a mixture of (i) urethane acrylate resin particles; (ii) acrylic resin particles; and (iii) a matting agent. A method of imparting stain resistance to a substrate, comprising applying the coating composition to at least a portion of the substrate.

A method for forming an emulsion polymer includes a step of forming a pre-emulsion by combining a monomer composition with a siloxane-containing composition in water and polymerizing the pre-emulsion by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture. Characteristically, the monomer composition includes one or more monomers selected from the group consisting of (meth)acrylic acid monomers, (meth)acrylic monomers, styrene monomers, vinyl acetate monomers, vinyl ester monomers, and combinations thereof. A paint composition that includes the emulsion polymer is also provided. This invention describes a method to provide excellent burnish and mar resistance while avoiding problems with film appearance that can result from siloxane addition.
