Abstract
A method for producing a molded silicone rubber product comprising(i) forming a mixture comprising(A) a primary composition in the form of a paste comprising an inorganic filler and a diorganopolysiloxane containing at least 2 silicon atom-bonded alkenyl groups per molecule,(B) a liquid catalyst composition comprising a platinum catalyst and an organopolysiloxane containing at least 2 silicon atom-bonded alkenyl groups per molecule, and(C) a liquid curing composition comprising an organopolysiloxane having at least 2 silicon atom-bonded hydrogen atoms per molecule and an organopolysiloxane having at least 2 silicon atom-bonded alkenyl groups per molecule;(ii) feeding the mixture comprising components (A), (B), and (C) into a molding device; and(iii) curing the mixture comprising components (A), (B), and (C) by heating.
