<P>PROBLEM TO BE SOLVED: To provide an addition-curable self-adhesive silicone rubber composition adherable to a wide variety of metals or resins, and moldable in a short period of time. <P>SOLUTION: The addition-curable self-adhesive silicone rubber composition comprises (A) 100 pts.mass of an organopolysiloxane containing at least two alkenyl groups bonded to silicon atoms in the molecule, (B) 0.2-30 pts.mass of an organohydrogenpolysiloxane containing at least three hydrogen atoms bonded to silicon atoms in the molecule, which is represented by formula (1) (wherein R<SP POS="POST">1</SP>is a monovalent hydrocarbon group; R<SP POS="POST">2</SP>is R<SP POS="POST">1</SP>or H; X is a divalent organic group; A is a monovalent organic group containing aromatic ring; n is 3-150; m is 1-30; p is 0-100; and n+m+p is 10-200), (C) 0-30 pts.mass of an aromatic ring-free organohydrogenpolysiloxane containing at least two hydrogen atoms bonded to silicon atoms in the molecule, and (F) an addition reaction catalyst, wherein the molar ratio of the total SiH functional group of the components (B) and (C) to the alkenyl group of the component (A) is 0.8-5.0. <P>COPYRIGHT: (C)2012,JPO&INPIT |
