Glycol ether amines for aqueous two-component polyurethane coating

Abstract

The present invention provides aqueous compositions comprising (i) an aqueous acrylic or vinyl polymer dispersion wherein the polymer comprises an average of two or more hydroxyl groups or contains a polyol, (ii) one or more pigments, extenders or colorants, or their combination, and, (iii) one or more glycol ether amines having the following formula I: wherein R1 is a C1 to C6 alkyl group, or, preferably, a C3 to C4 alkyl group, R2 and R3 are, independently, CH3 or CH2—CH3; and, m is 1 to 6, or, preferably, from 1 to 2. The aqueous composition may further comprise a water dispersible polyisocyanate curing agent, thereby forming a curable aqueous coating composition that forms a polyurethane coating or film.
