SILICONE RUBBER COMPOSITION AND CURED ARTICLE THEREOF

摘要

PURPOSE:To obtain a silicone rubber composition having self-bonding properties and cured product thereof by blending a specific addition reaction-curing type silicone rubber composition with a specific alkoxyhydrodiene siloxane and epoxy group-containing polysiloxane. CONSTITUTION:The aimed composition obtained by blending (A) vinyl group- containing diorganopolysiloxane having >=2 bonds expressed by formula I in one molecule with (B) organohydrodienepolysiloxane having >=2 Si-bonded hydrogens in one molecule, (C) platinum or platinum compound, (D) alkoxyhydrodiene siloxane expressed by formula II (R<1> is monovalent hydrocarbon group containing no aliphatic unsaturated bond; n is 0 or positive ingredient) of 0.01-5wt.% based on total amount of the components A and B and (E) epoxy group-containing polysiloxane compound having >=1 epoxy group bonded through carbon atom to Si of 0.1-5wt.% based on total amount of the components A and B.
