Patent ID: 8030427

Claim:
A curable composition comprising (A) 100 parts by weight of an organic polymer having a silicon-containing group capable of being crosslinked by forming a siloxane bond, wherein the main chain skeleton of the organic polymer for component (A) is at least one kind of polymer selected from the group consisting of a polyoxyalkylene polymer, a saturated hydrocarbon polymer and a (meth)acrylic acid ester polymer, (B) 0.001-20 parts by weight of a divalent tin carboxylate which is not an organotin catalyst having a carbon-tin bond, (C) 0.01-20 parts by weight of a silane coupling agent free of an amino group, and (D) an unsubstituted amino group-containing compound in an amount corresponding to a weight ratio with component (B) of 0.029, wherein a silicon-containing group wherein three hydrolyzable groups or hydroxyl groups are bonded to a silicon atom is contained as an essential silicon-containing group of component (A).
