Abstract
An organopolysiloxane composition, comprising PA0 (A) an organopolysiloxane having alkenyl groups bonded to silicon atoms, PA0 (B) an organohydrogenpolysiloxane having two or more hydrogen atoms bonded to silicon atoms, and PA0 (C) an addition reaction catalyst, wherein the vinyl group containing organopolysiloxane (A) as a base polymer and the organohydrogenpolysiloxane (B) as a crosslinking agent each have at least two alkoxy group and/or at least one epoxy group in the molecule. By subjecting this composition to addition curing, a gel cured product excellent in adhesion particularly to metals is obtained.
