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.
