Abstract
A silicone rubber composition is disclosed. The silicone rubber composition comprises: (A) an organosiloxane having at least two alkenyl groups in each molecule; (B) a silica filler; (C) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms in each molecule; (D) a hydrosilylation reaction catalyst; and (F) an adhesion promoter. Component (B) is prepared by surface-treating a silica filler with (E) a surface treatment agent in the presence of part or all of component (A). The silicone rubber composition generally exhibits excellent adhesion to various organic resins in contact during curing while simultaneously exhibiting excellent mold releasability with respect to a mold used for the molding thereof.
