Room-Temperature-Curable Silicone Rubber Composition

摘要

A room-temperature-curable silicone rubber composition comprises: (A) an organopolysiloxane having on silicon atoms in the molecular chain in one molecule at least two specific alkoxysilyl-containing groups; (B) an organopolysiloxane having on silicon atom in the molecular chain neither a hydroxyl group nor an alkoxy group; (C) an alkoxysilane or its partial hydrolysis and condensation product; (D) a condensation reaction catalyst; and optionally comprises (E) an adhesion promoter and/or (F) a re-inforcing filler. The composition cures at room temperature due to contact with atmospheric moisture and exhibits an excellent adhesiveness to substrate in contact with the composition during the cure of the composition.
