This invention is directed to high solids coating compositions comprising a hydroxyl functional acrylic polymer, an alkylolated melamine and, as a reactive diluent, a polycaprolactone polyol, wherein the ratio of the equivalent weight of the alkylolated melamine to the total hydroxyl equivalent weight of the hydroxyl functional acrylic polymer and the polycaprolactone polyol is from about 0.8 to about 2.5. The high solids coating compositions have utility as automotive finishes, appliance finishes, general metal finishing and the like.
本发明涉及高固体份涂料组合物,该组合物包含羟基官能丙烯酸聚合物、烷基醇化三聚氰胺和作为活性稀释剂的聚己内酯多元醇,其中烷基醇化三聚氰胺的当量重量与羟基官能丙烯酸聚合物和聚己内酯多元醇的羟基当量总重量之比约为 0.8 至 2.5。这种高固体分涂料组合物可用作汽车面漆、家电面漆、普通金属面漆等。
