An improved urethane acrylate gel coat resin, its method of manufacture, and its use in gel coat compositions are disclosed. The urethane acrylate gel coat resin contains terminal acrylate moieties and is the reaction product of an oligoester of weight average molecular weight about 200 to about 4000, a diisocyanate, and a hydroxyalkyl (meth)acrylate. The gel coat resin is used in gel coat compositions that exhibit good weatherability and color stability after cure.
本发明公开了一种改进型聚氨酯丙烯酸酯胶衣树脂、其制造方法及其在胶衣组合物中的用途。聚氨酯丙烯酸酯胶衣树脂含有末端丙烯酸酯分子,是重量平均分子量约 200 至约 4000 的低聚物、二异氰酸酯和羟基烷基(甲基)丙烯酸酯的反应产物。胶衣树脂可用于胶衣组合物,固化后具有良好的耐候性和颜色稳定性。
