A one-can resin composition which contains:
(1) a blocked polyisocyanate produced by blocking, with an oxime type blocking agent, α,α,αʹαʹ-tetra-methylxylylene diisocyanate or a terminal NCO-containing prepolymer formed by reaction of said diisocyanate with an active hydrogen-containing compound,
(2) a polyol compound and
(3) a monoalcohol.
The resin composition, when stored at 40°C, is stable for at least 3 months. It can be cured at temperatures as low as 90-120°C. Therefore, it can be used advantageously as a baking paint for automotive exterior coating, cationic electro-deposition coating, coating of household electric appliances, and enameled wire manufacture, among others.
一种单罐树脂组合物,其中含有
(1) 一种封端多异氰酸酯,由α,α,αʹαʹ-四甲基亚甲基二异氰酸酯或由上述二异氰酸酯与活性含氢化合物反应生成的含 NCO 的封端预聚物与一种肟型封端剂封端而成、
(2) 多元醇化合物和
(3) 一种单醇。
该树脂组合物在 40°C 下储存至少 3 个月。它可以在低至 90-120°C 的温度下固化。因此,该树脂组合物可用作汽车外涂层、阳离子电沉积涂层、家用电器涂层和漆包线制造等领域的烘烤漆。
