    摘要: An addition-curable type silicone rubber composition comprising (A) an organopolysiloxane having an alkenyl group such as vinyl in its molecule, (B) an organohydrogenpolysiloxane having at least two SiH groups in its molecule, (C) a platinum catalyst such as platinum, chloroplatinic acid, etc., (D) an inorganic filler, (E) an organic titanium compound such as tetraethyl titanate, and (F) water. The composition exhibits good fluidity, and behaves like a Newtonian fluid, even where carbon black or a silica or alumina having an average particle diameter of 1 .mu.m or above is incorporated in the composition as an inorganic filler for improving such characteristics as heat resistance, thermal conductivity, etc.
