Abstract
The invention is a method for making reaction injection molded polyurethane of improved paintability properties. The product comprises the reaction product of a high molecular weight polyhydric polyether, a low molecular weight active hydrogen containing compound of at least two functionality, a polyisocyanate and a catalyst combination comprising N,N-Dimethylethanolamine, dibutyltin dilaurate and an alkyltin mercaptide. This catalyst combination results in improved processing, a minimum of surface defects, excellent green strength and improved paintability using certain paints. Reaction injection molded elastomers are useful as molded articles of commerce including, but not limited to, vehicle body parts.
