MULTICOMPONENT ROOM TEMPERATURE-CURABLE ORGANOPOLYSILOXANE COMPOSITION, CURED PRODUCT OF SAID COMPOSITION, AND MOLDED PRODUCT COMPRISING SAID CURED PRODUCT

摘要

Provided is a multicomponent room temperature-curable organopolysiloxane composition capable of providing a cured product superior in fast curability, storage stability and durability. The room temperature-curable organopolysiloxane composition comprises:
(A) an alkoxysilyl-ethylene group-terminated organopolysiloxane having in each molecule at least one silyl-ethylene bond represented by the following structural formula (1)
(wherein R 1 represents an alkyl group; R 2 represents a hydrocarbon group having 1 to 20 carbon atoms; a represents an integer of 1 to 3; and n represents an integer of 0 to 10.);
(B) an organopolysiloxane represented by the following general formula (2)
(wherein R 2 represents a hydrocarbon group having 1 to 20 carbon atoms; and m represents a number at which such organopolysiloxane exhibits a viscosity of 10 to 1,000,000 mPa·s at 25°C.); and
(C) a curing catalyst.
