Abstract:
1. A curable composition comprising: 100 parts by weight of an organic polymer (A) containing at least one silyl group that contains a hydroxy or hydrolyzable group bonded to a silicon atom and can form a siloxane bond to be cross-linked; 0.1 to 10 parts by weight of a silanol condensation catalyst (B); and a silane coupling agent (C) that contains a primary amino group, the silyl group in the organic polymer (A) being a group represented by formula (5): wherein R the silanol condensation catalyst (B) being a reaction product of a dialkyltin dicarboxylate represented by the following formula (1) and a tetraalkoxysilane represented by the following formula (2) and/or its partially hydrolyzed condensate, the formula (1) being wherein R the formula (2) being wherein R the silane coupling agent (C) that contains a primary amino group being an amino silane coupling agent that contains an —NH wherein R wherein R the curable composition having a content of an amino silane coupling agent (C1) with b in formula (3) being 3 of 1 to 10 parts by weight, and having a content of an amino silane coupling agent (C2) with b in formula (3) being 1 or 2 of less than 1 part by weight.
