ABSTRACT:
Two-component polyurethane coating formulations comprising an aqueous dispersion of a polyisocyanate and a neutralized, water-dispersible resin are disclosed. The neutralized, water-dispersible resin incorporates recurring units of an allylic alcohol or an alkoxylated allylic alcohol. These low-VOC formulations use commercial polyisocyanates and ordinary mixing techniques. The uniquely uniform distribution of hydroxyl groups in the resin contributes to an excellent overall balance of coating properties from the 2K system, including high gloss, hardness, impact resistance, flexibility, weatherability, and chemical resistance.
