PRODUCTION OF SILICONE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a vacuum dispensable silicone composition. SOLUTION: This method for producing a silicone composition comprises (I) process for mixing (A) a polyorganosiloxane containing at least two alkenyl groups bound to silicon in the molecule on the average, (B) an organopolysiloxane resin substantially comprising siloxane units of the formula: R<3> 3 (CH2 =CH)SiO1/2 , siloxane units of the formula: R<3> 3 SiO1/2 and siloxane units of the formula: SiO4/2 , (C) an organo hydrogen polysiloxane having at least three hydrogen atoms bound to silicon per molecule on the average, (D) an adhesion accelerator, (E) a hydrosilylation catalyst, and (F) a platinum catalyst inhibitor, and (II) a process for degassing the mixture to produce the composition substantially not containing air.
