ABSTRACT:
A novel curable organopolysiloxane-epoxy resin composition, which is capable of giving a cured body having excellent mechanical properties without the problem of adhesion to the metal mold, is proposed. The composition comprises: (a) an epoxy resin; (b) an organopolysiloxane containing vinyl groups; (c) an organohydrogenpolysiloxane as the crosslinking agent of the component (b); (d) a platinum compound as a catalyst for the hydrosilation reaction; and (e) a specific organic aluminum compound, such as tris(acetylacetonato) aluminum, each in a specified proportion.
