Abstract:
1. A curable composition, comprising: an organic polymer (A) containing on average at least 1.4 reactive silyl groups per molecule; an organic polymer (B) containing on average less than 1 reactive silyl group per molecule, and an organotin curing catalyst (C); wherein the number average molecular weight of component (B) is lower than the number average molecular weight of component (A) by at least 3,000, and the ratio (y)/(x) of the number of moles (y) of organic polymers each containing only one reactive silyl group per molecule among components (A) and (B) to the number of moles (x) of organic polymers each containing at least 2 reactive silyl groups per molecule among components (A) and (B) is not more than 5.
