PURPOSE:To obtain a room-temperature-curable compsn. which is cured into a silicone rubber having a low modulus and a high elongation by compounding an organopolysiloxane with an inorg. filler, an organoalkoxysilane, an organohydrogenpolysiloxane, and a tin catalyst. CONSTITUTION:The compsn. comprises 100 pts.wt. diorganopolysiloxane having molecular terminals blocked by hydroxyl groups and a viscosity at 25 deg.C of 100-1,00,000cSt, 1-300 pts.wt. inorg. filler, 0.5-30 pts.wt. organoalkoxysilane or organoalkoxypolysiloxane having at least three alkoxy groups directly bonded the Si atoms in the molecule, 0.2-20 pts.wt. organohydrogenpolysiloxane having at least one H atom directly bonded to the Si atom in the molecule, and 0.001-10 pts.wt. tin catalyst. |
