Abstract
Abstract The present invention has its object to provide a curable composition insuring a reduced stress without sacrificing restoring force and other physical properties and having a sufficient degree of adhesiveness.The present invention is related to a curable composition comprising comprising an oxyalkylene polymer having at least one reactive silicon group per molecule (A-1),an acid (B),an amine (C), anda tin-series curing catalyst (D).This composition optionally contains a vinyl polymer having at least one reactive silicon group.

Claim 2
Dependent Claim
61 words
A one-component curable composition with a long shelf-life which is stored in a hermetically sealed condition, comprising an oxyalkylene polymer having at least one reactive silicon group per molecule (A-1), an acid (B), an amine (C), and a tin-series curing catalyst (D), said acid (B and said amine (C) being contained respectively in molar excess over the tin-series curing catalyst (D).
Claim 3
Dependent Claim
221 words
