(57) [Summary] [Problem] To provide a room-temperature fast-curing silicone composition which is excellent in curability, durability and storage stability while sufficiently exhibiting the inherent properties of the silicone composition. SOLUTION: (A) 100 parts by weight of an organopolysiloxane having a terminal blocked with a hydroxyl group and having a viscosity at 25 ° C of 25 to 1,000,000 mPa · s (B) hydrolysis represented by the following general formula (1) At least one compound selected from functional silanes and partial hydrolysates thereof 2 to 50 parts by weight R n SiX 4-n (1) (wherein R is the same or different, unsubstituted or substituted C 1-12 A monovalent hydrocarbon group, X is at least one group selected from a ketoxime group, an alkoxy group, an alkenoxy group and an acyloxy group, and n is an integer of 0 to 2) (C) a water-containing wet method having an average particle size of 100 μm or less. A room temperature fast-curing silicone composition comprising 3 to 200 parts by weight of silica, wherein the component (C) is a main source of water necessary for a condensation curing reaction. |
