PURPOSE:To obtain the subject composition having improved dripping properties in compounded state by mixing organosilane or partially hydrolyzed condensate of said organosilane, fine powdery silica and catalyst for curing in specific ratio. CONSTITUTION:(A) 100 pts.wt. polyorganosiloxane having at least two hydroxyl groups bonded with silicon atom in a molecule and 10<2>-5X10<5>cp viscosity at 25 deg.C is previously mixed with (B) 1-30 pts.wt. organosilane containing at least two ketoxime groups bonded with silicon atom in a molecule and/or partially hydrolyzed condensate of said organosilane in fixed ratio and resultant mixture is mixed with (C) 1-50 pts.wt. fine powdery silica and (D) 0.01-10 pts.wt. catalyst for curing in fixed ratio. |
