    摘要: The present invention is directed to waterborne curable film-forming compositions comprising a film-forming resin, a crosslinking agent, and an additive comprising isostearic acid neutralized with dimethylethanolamine. The compositions are essentially free of additives derived from reaction products of isocyanate functional materials and alkoxypolyalkylene compounds.The present invention further provides multi-component composite coating compositions comprising a first film-forming composition applied to a substrate to form a primer or base coat, and a second film-forming composition applied on top of the primer or base coat to form a top coat, the top coat comprising the composition described above.Coating compositions prepared from the curable compositions of the present invention demonstrate superior pop resistance properties, making them ideally suited for automotive applications.
