A one-pack curing composition which comprises (a) a compound having two or more structural groups represented by general formula (I) (wherein R1, R2 and R3 each represents a group selected from among C1-C8 alkyl groups, a phenyl group, and a chloromethyl group) per molecule and (b) a polymer having two or more isocyanato groups per molecule. This composition shows a good storage stability under a moisture- free condition and is curable in the presence of moisture. This composition does not foam even at high temperatures and high humidities, and shows good heat resistance.
一种单组分固化组合物,它包括:(a) 每分子具有两个或两个以上通式 (I) 所代表结构基团的化合物(其中 R1、R2 和 R3 各代表一个从 C1-C8 烷基、苯基和
氯甲基中选出的基团);(b) 每分子具有两个或两个以上异
氰酸基的聚合物。这种组合物在无湿条件下具有良好的储存稳定性,并可在有湿气的情况下固化。即使在高温和高湿度条件下,这种组合物也不会起泡,并具有良好的耐热性。
