Patent ID: 8580889

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 eight silicon-bonded hydrogen atoms in a molecule, having the general formula (1): wherein R 1 is each independently an unsubstituted or halo or cyano-substituted monovalent hydrocarbon group of 1 to 5 carbon atoms, R 2 is R 1 or hydrogen, R 3 is R 1 or an aromatic ring-containing monovalent organic group of 6 to 10 carbon atoms, X is a single bond or 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, B is a monovalent reactive organic group of 3 to 9 carbon atoms, n is a positive number of 8 to 150, m is a positive number of 1 to 30, p is a positive number of 1 to 30, q is a number of 0 to 100, and the sum of n+m+p+q is 10 to 200, (C) 0 to 30 parts by weight of an organohydrogenpolysiloxane containing at least two silicon-bonded hydrogen atoms in a molecule and no reactive groups other than the SiH groups, and (F) a catalytic amount of an addition reaction catalyst, a molar ratio of total SiH functional groups in components (B) and (C) to alkenyl groups in component (A) being in a range of from 0.8 to 5.0.
