Abstract:
1. A composite cured product body comprising 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, wherein said addition reaction curable organopolysiloxane composition comprises: (A) 100 parts by weight of an organopolysiloxane with at least 2 alkenyl groups bonded to silicon atoms within each molecule, (B) an organohydrogenpolysiloxane with at least 2 hydrogen atoms bonded to silicon atoms within each molecule, in sufficient quantity that a number of hydrogen atoms bonded to silicon atoms within a single molecule is within a range from 1 to 7 per alkenyl group within said organopolysiloxane of component (A), (C) an effective quantity of a hydrosilylation reaction catalyst, and (D) 1 to 50 parts by weight of at least one organopolysiloxane containing, within each molecule, at least one monovalent group bonded to a silicon atom and represented by either a formula (1) shown below: wherein, each R represents, independently, an unsubstituted or substituted monovalent hydrocarbon group of 1 to 10 carbon atoms, or a formula (2) shown below: wherein, R 1 represents an oxygen atom or an alkylene group of 2 or more carbon atoms, each R 2 represents, independently, an alkyl group, each R 3 represents, independently, an unsubstituted or substituted monovalent hydrocarbon group of 1 to 10 carbon atoms, and a represents an integer from 1 to 3.
