An addition product obtained by reacting (a) a polyfunctional epoxy compound and (b) a compound having at least one functional group of OH group, SH group, COOH group and CONHNH2 group together with a tertiary amino group in the molecule, and an addition product obtained (a), (b) and (c) an organic compound having two or more active hydrogen atoms in the molecule (excluding a compound having an epoxy group or tertiary amino group) are good curing agents for epoxy resin. The curing agents are useful in formulating novel storable one-package, heat-curable epoxy resin-based compositions.
将(a)多官能团环氧化合物和(b)分子中含有至少一个羟基、SH 基、COOH 基和 CONHNH2 基官能团的化合物与分子中的叔
氨基反应得到的加成产物,以及将(a)、(b)和(c)分子中含有两个或两个以上活泼氢原子的有机化合物(不包括具有环氧基团或叔
氨基的化合物)反应得到的加成产物是环氧
树脂的良好固化剂。这些固化剂可用于配制新型可储存的单组分热固化环氧
树脂基组合物。
