A resin composition, which comprises (a) a copolymer containing isocyanate group prepared by subjecting a compound represented by the general formula
wherein R₁ stands for hydrogen or methyl group and an ethylenic unsaturated monomer to copolymerization, and (b) a copolymer containing amino group prepared by subjecting a compound represented by the general formula
wherein R₂ stands for hydrogen or methyl group and an ethylenic unsaturated monomer to copolymerization, has a pot life of such an extent as for permitting them to be used as spray-coating, and the resulting film is excellent in flexibility, chemical resistance, water resistance and corrosion resistance, and, besides, rapid in curability, thus being useful as cold-drying coatings on metals, plastics, woods, inorgainc materials, etc. and also as adhesives, etc. The resin composition is very good in compatibility, thus being useful in such a field as required high gloss and beautiful finish. Further, the amino group containing copolymer is of relatively high molecular weight, thus being of less toxicity, and, besides, substantially odorless, and, therefore, it causes no injurious problems to health and safety.
一种树脂组合物,它包括(a)通过使通式为
其中 R₁ 代表氢或甲基和乙烯基不饱和单体进行共聚,以及 (b) 一种含有氨基的共聚物,该共聚物是通过将通式所代表的化合物
其中 R₂ 代表氢或甲基和乙烯基不饱和单体进行共聚而制备的含氨基的共聚物,具有一定的罐装寿命,可用作喷涂涂层,所得薄膜具有优异的柔韧性、耐化学性、耐水性和耐腐蚀性,而且固化速度快,因此可用作金属、塑料、木材、非金属材料等的冷干涂层,也可用作粘合剂等。这种树脂组合物的相容性非常好,因此在要求高光泽和美观的领域非常有用。此外,含氨基的共聚物分子量相对较高,因此毒性较低,而且基本上没有气味,因此不会对健康和安全造成危害。
