Abstract
Abstract The present invention provides a one-part curable composition, comprising (A) an organic polymer having a silicon-containing group capable of cross-linking by forming siloxane bonds; (B) a metal carboxylate; and (C) a carboxylic acid smaller in molar quantity than the (B) component metal carboxylate, the one-part curable composition being simultaneously practical in recovery ratio, durability, creep resistance, storage stability and adhesion.
