Description

ABSTRACT:
A room temperature curable rubber composition of a condensation curing type that comprises as a base polymer a diorganopolysiloxane or a polyoxyalkylene in which both ends of the molecular chain are blocked with a hydrolyzable silyl group, and a carbonyl compound, an amino group containing organic compound, and an .alpha.,.beta.-unsaturated carbonyl compound that are blended with the base polymer. Since the room temperature curable rubber composition is cured with water in the air and at the same time the dehydration condensation of the carbonyl group and the amino group produces water in the composition, the quick curability and deep curability are improved remarkably.
