Addition reaction curable organopolysiloxane composition

摘要

A composite cured product body is provided, which includes a first cured product part formed from a condensation reaction curable silicone rubber, and a second cured product part adhering to a surface of said first cured part formed from an addition reaction curable organopolysiloxane composition. The addition reaction curable organopolysiloxane composition includes: (A) an organopolysiloxane with at least 2 alkenyl groups bonded to silicon atoms, (B) an organohydrogenpolysiloxane with at least 2 hydrogen atoms bonded to silicon atoms, (C) a hydrosilylation reaction catalyst, and (D) at least one organopolysiloxane with at least one monovalent group bonded to a silicon atom and represented by the formula (1): -O-SiR2(OH) (1) or the formula (2): -R<1>-Si(OR<2>)aR<3>3-a (2).
