Patent ID: 8362141

Claim:
An addition curable self-adhesive silicone rubber composition, comprising (A) 100 parts by weight of an organopolysiloxane containing at least two silicon-bonded alkenyl groups in a molecule; (B) 0.2 to 30 parts by weight of an organohydrogenpolysiloxane containing at least three silicon-bonded hydrogen atoms in a molecule, represented by formula (1): wherein each R 1 is independently an unsubstituted or halo or cyano-substituted monovalent hydrocarbon group of 1 to 5 carbon atoms, R 2 is R 1 or hydrogen, X is a divalent organic group of 1 to 5 carbon atoms, A is an aromatic ring-containing monovalent organic group of 6 to 10 carbon atoms, n is a positive number of 3 to 150, m is a positive number of 1 to 30, p is a number of 0 to 100, and n+m+p is from 10 to 200; (C) 0 to 30 parts by weight of an aromatic ring-free organohydrogenpolysiloxane containing at least two silicon-bonded hydrogen atoms in a molecule; (E) 0.5 to 25 parts by weight of an adhesive auxiliary, which is an organosilicon compound having in a molecule an epoxy group and at least one group selected from an alkoxysilyl group and a silanol group; and (F) a catalytic amount of an addition reaction catalyst, wherein a molar ratio of total SiH functional groups in components (B) and (C) to alkenyl groups in component (A) is in a range of 0.8 to 5.0.
