AQUEOUS COATING COMPOSITIONS HAVING LOW OR ZERO VOCS AND COMPRISING ENCAPSULATED OR POLYMER ADSORBED PIGMENTS AND LETDOWN BINDERS
The present invention provides aqueous compositions useful as zero VOC coating compositions having a % opacifying pigment volume concentration (% OPVC) of from 2 to 25 and comprising (i) an opacifier composition of an at least partially polymer encapsulated opacifying pigment, a polymer opacifying pigment composite or their mixtures, with the opacifying pigment, encapsulated in and/or as a composite with at least one soft polymer having a measured glass transition temperature (measured Tg) of 5° C. or less, and (ii) a hard binder polymer having a measured Tg of at least 30° C. and a weight average particle size of 120 nm or less, wherein the ratio of the weight average particle size of the opacifier composition to that of the hard binder polymer is from 2:1 to 12:1 and the volume ratio of the opacifying pigment to the soft polymer solids in the opacifier composition is from 2:5 to 1:1
Liquid formulations for coating and printing substrates
A method is disclosed of preparing a liquid formulation for application as a deposit on a substrate. The method includes the steps of providing a liquid having a first viscosity in a non-evaporative state; and adding an amine-acid adduct to the liquid to form a mixture having a second viscosity greater than the first viscosity. The amine-acid adduct is evaporative such that the amine-acid adduct is substantially completely removed from the deposit in a functionally dry state.
AQUEOUS COATING COMPOSITION COMPRISING A THICKENER PREPARABLE FROM AT LEAST ONE POLYAMIDE AND AT LEAST ONE FURTHER POLYMER
The present invention relates to an aqueous coating composition comprising at least one binder (A) comprising at least one polymeric resin (A1), at least one pigment (B), and an aqueous dispersion of at least one thickener (C), where (C) is obtainable by a method comprising at least the steps (1), (2), (3), and (4), namely preparing a dispersion or solution of at least one polyurethane as a polymeric resin (C2) in at least one organic solvent (step (1)), preparing a mixture of the dispersion or solution obtained by step (1) and of a melt or solution of at least one polyamide as at least one polymeric resin (C1) having an acid number in a range from 1 to 200 mg of KOH per g of (C1) (step (2)), adding water to the mixture obtained by step (2) (step (3)), and removing the organic solvent from the mixture obtained by step (3), to give the aqueous dispersion of (C) (step (4)), to the use thereof for at least partly coating an optionally coated substrate with a basecoat film, to a coating method of this kind, and to a substrate coated accordingly.

NON-SKID, TEXTURED PROTECTIVE COATING COMPOSITIONS FOR VEHICLE SURFACES
In general, the embodiments herein provide non-skid, textured protective coating compositions for vehicle surfaces, such as vehicle beds, rocker panels, inner fenders, tailgates, bedrails, cargo vans, step area, and running boards, and other applicable metal, aluminum, fiberglass, plastic, and wood surfaces, and the method for producing same. In particular, embodiments of the present disclosure relate to textured protective coating compositions having improved impact, abrasion, and chemical resistance. These properties are obtained by a combination of an acrylic resin component and a solvent composition, and optionally a rheology additive component, a texturizing component, an adhesion promoter, and a plasticizer.
POLYESTERS
The present invention provides a polyester which is the reaction product of reactants comprising: (A) an aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms; (B) an aromatic carboxylic acid and/or anhydride; and (C) a polyol. The invention also provides a coating composition comprising the polyester, a method of making the coating composition and the use of at least 2 wt % of a linear aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms as a replacement for at least 2 wt % of an aromatic carboxylic acid and/or anhydride in a polyester composition. This use may improve the UV resistance and/or stability of the polyester composition.
