Two-part curable liquid silicone composition

摘要

A two-part composition comprising a liquid composition (I) composed of the components (A), (C), and (E) described below and a liquid composition (II) composed of the components (A) (B), (C), and (D) described below, which yield upon mixing a curable liquid silicone composition comprising (A) an alkenyl-substituted poyorganopolysiloxane; (B) a hydrogen-substituted organopolysiloxane in an amount that provides 0.3 to 10 moles silicon-bonded hydrogen from component (B) per 1 mole alkenyl in component (A); (C) an inorganic filler that has a specific surface of 50 to 500 m2/g; (D) an alkoxy-substituted organopolysiloxane; and (E) platinum catalyst in a quantity sufficient to cure the instant composition; wherein the curable silicone composition that results when liquid composition (I) and liquid composition (II) are mixed, is thixotropic and has a viscosity, immediately upon the mixing that is greater than the viscosity of liquid composition (II).
