Abstract
An improved thickening composition for aqueous systems including latex paints and coatings is described. The substantially anhydrous composition comprises in specified ratios a solid thickener polymer, and one or more surfactants. The solid thickener polymer includes associative thickeners. Associative thickener polymers include polyurethanes, polyesters, polyacrylamides, modified hydroxyethyl celluloses, alkali soluble emulsions and other chemicals. Specific surfactants utilized include dialkyl sulfosuccinates, alkyl sulfates, alpha olefin sulfonates and sulfates of ethoxylated alcohols.
