Abstract: Provided herein are self-adhesive curable silicone rubber compositions. When cured, the curable silicone rubber compositions generally achieve significant adhesion to plastic/thermoplastic/resin material substrates, and especially adhesion to polycarbonate materials. Also provided herein is a process for preparing plastic/thermoplastic/resin materials, especially polycarbonate/cured silicone elastomer materials, and articles and composite parts made from such curable silicone rubber compositions. The silicone rubber compositions generally comprise one or more organopolysiloxanes containing at least 2 alkenyl groups per molecule and having a viscosity of greater than 1,000,000 mPa·s at 25° C.; an organopolysiloxane containing at least 2 silicon-bonded hydrogen atoms per molecule; a platinum group catalyst; reinforcing and/or non-reinforcing fillers; and one or more rubber modified epoxy resins.
