PURPOSE:To obtain the title composition excellent in, e.g. the capability of forming a thin coating film by mixing specified diorganopolysiloxane, filler, organohydrogenpolysiloxane, catalyst and organosilicon compound and an organopolysiloxane resin each in a specified amount. CONSTITUTION:The title composition consists of 100 pts.wt. diorganopolysiloxane (A) having at least two alkenyl groups in the molecule (e.g. dimethylpolysiloxane having both terminals blocked with dimethylvinylsiloxy groups), 5-100 pts.wt. inorganic filler (e.g. silica), an organohydrogenpolysiloxane containing at least two hydrogen atoms bonded to the Si atom in the molecule, in an amount sufficient to provide a molar ratio of the hydrogen atoms to the alkenyl groups of component A of (0.6:1) to (20:1), a platinum catalyst in an amount of 0.1-500 pts.wt. based on 1,000,000 pts.wt. component A, 0.1-20 pts.wt. organosilicon compound containing epoxy group(s) (e.g. gamma-glycidoxypropyltrimethoxysilane), and 5-100 pts.wt. organopolysiloxane resin. |
