Silicone rubber compositions

A self-adhesive curable silicone elastomer composition that can achieve adhesion on plastic/thermoplastic/resin material substrates, the self-adhesive curable silicone elastomer composition comprising:

• (A) one or more organopolysiloxanes containing at least 2 alkenyl groups and/or alkynyl groups per molecule and having a viscosity in a range of 1,000 to 200,000 mPa·s at 25° C.;
• (B) an organopolysiloxane containing at least 2 or 3 silicon-bonded hydrogen atoms per molecule;
• (C) at least one hydrosilylation catalyst;
• (D) at least one reinforcing filler and optionally one or more non-reinforcing fillers;
• (E) an adhesion promoter;
• and
• (F) an oligomer of the formula;
• (R3O)3Si—X—(SiR32—O)y(SiR32—X)n—(SiR32—O)z—Y—(O—SiR32)z(XSiR32)n(O—SiR32)y—X—Si(OR3)3
• wherein
• Y is —SiR12—, —SiR1R2— or —SiR3R1—O—R3R1Si—;
• each R3 may be the same or different and is an alkyl group having 1 to 6 carbons;
• each X may be the same or different and is an alkylene group having from 1 to 6 carbons;
• each R1 is a phenyl group;
• each R2 is —(O—SiR32)z(XSiR32)n(O—SiR32)y—X—Si(OR3)3;
• and
• y is zero or an integer up to 6, n is 0 or 1, and z is 0 or 1;
• with the proviso that z is 0 when n is 0 and y is greater than zero.
