ABSTRACT:
A process for wet mixing a silicone molding composition comprising mixing a silicone resin and a hydrocarbon solvent to form a solution of 10 to 50% by weight of solids and adding to the slurry a variety of fillers, a silicone plasticizer, a pigment and a catalyst to form a paste of about 85 to 95% by weight of solids; kneading the paste to thoroughly mix the ingredients and form a homogeneous mixture; and then removing most of the solvent and breaking of the composition left behind to form the appropriate size particles of a uniformly homogeneous silicone molding composition.
