<P>PROBLEM TO BE SOLVED: To provide a composite rubber having good adhesiveness. <P>SOLUTION: The composite rubber, having good adhesiveness between crosslinked rubbers of same kind without using a primer, is obtained by using curable compositions comprising: (A1) and (A2) of oxyalkylene-based polymers having more than one alkenyl groups in a molecule and silicone-based polymers; (B1) and (B2) of compounds having at least two hydrosilyl groups in a molecule; and (C1) and (C2) of hydrosilylation catalysts, and by regulating blending amounts of (B1) and (B2), heating temperature conditions and compositing conditions. <P>COPYRIGHT: (C)2012,JPO&INPIT |
