Patent ID: 10294346

Abstract:
An organic modified silicone resin composition includes: (A) an addition reaction product having two addition reactive carbon-carbon double bonds in one molecule, being a product of an addition reaction of (a) a compound shown by the general formula (1) having SiH groups and (b) a polycyclic hydrocarbon having addition reactive carbon-carbon double bonds; (B) a siloxane having an SiH group and an organic group substituted with an alkoxysilyl group and/or a siloxane having an SiH group and an organic group substituted with an epoxy group; (C) a compound having three or more SiH groups in one molecule; (D) a catalyst; and (E) fumed inorganic oxide. The formulation amount of the component (E) is 1 to 10 parts by mass relative to 100 parts by mass of the total amount of the components (A), (B), and (C); and having a viscosity of 10 to 100 Pa·s at 25° C.
