Abstract
A room-temperature-curable silicone rubber composition comprising (A) 100 parts by weight of a polydiorganosiloxan mixture comprising: (A-1) 20 to 95 wt. % of a polydiorganosiloxane having both molecular terminals capped with dialkoxysilyl groups or trialkoxysilyl groups, (A-2) 5 to 80 wt. % of a polydiorganosiloxane having a molecular terminal capped with dialkoxysilyl group or trialkoxysilyl group and the other molecular terminal capped with monoalkoxysilyl group, hydrosilyl group, trialkylsilyl group or trialkoxyalkylsilyl group, and (A-3) 0 to 30 wt. % of a polydiorganosiloxane having both molecular terminals capped with monoalkoxysilyl group, hydlosilyl group, trialkylsilyl group or trialkoxyalkylsilyl group, (B) one or more alkoxysilanes of the formula R5bSi(OR6)4-b or partial hydrolysis and condensation products thereof, and (C) an organotitanium compound. The composition is used as a sealant.
