Title:
GLYCOL ETHER AMINES FOR AQUEOUS TWO-COMPONENT POLYURETHANE COATING
Document Type and Number:
WIPO Patent Application WO/2024/020995
Kind Code:
A1
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 R 1 is a C 1 to C 6 alkyl group, or, preferably, a C 3 to C 4 alkyl group, R 2 and R 3 are, independently, CH 3 or CH 2-CH 3; 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.
