SILICONE RUBBER COMPOSITION FOR MOLD SURFACE RELEASE TREATMENT, AND METHOD FOR FORMING CURED SILICONE

WIPO Patent Application WO/2015/151480

A1

　A silicone rubber composition for mold surface release treatment, the silicone rubber composition comprising at least (A) alkenyl-group-containing organopolysiloxane represented by an average compositional formula, (B) a silica micropowder having a BET specific surface area of at least 50 m2/g, (C) organopolysiloxane having at least two silicon-atom-bonded hydrogen atoms per molecule, (D) a hydrosilylation reaction catalyst, and (E) a release component having an acid value of 5.0 mg/g or less and a melting point of 40-160ºC. Release treatment of the mold surface for heating and molding a curable silicone composition makes it possible to improve the cleaning cycle of the mold without triggering curing inhibition of the composition.
