ABSTRACT:
A condensation-curing type curable composition which comprises a diorganopolysiloxane or polyoxyalkylene blocked by hydrolyzable silyl group at both terminal ends of its molecular chain as a base polymer, in which a carbonyl group-containing organic compound and an amino group-containing organic compound are compounded. This composition is capable of forming water through dehydration condensation between carbonyl and amino groups, simultaneously with curing of the composition by moisture in air. The formation of water offers marked improvements in fast-curing property and also in depth curing property.
