| 摘要 |
The present invention is a room-temperature-curable organopolysiloxane composition containing as essential components (A) an organopolysiloxane shown by the following general formula (1), (B) an alkoxysilane shown by the following general formula (2) or a partial hydrolysate thereof, (C) a silazane compound shown by the following general formula (3), (D) a bismuth compound shown by the following general formula (4) which is in a liquid state at 20°C, a partial hydrolysate thereof, or both of them, (E) one or more fillers, and (F) a silane coupling agent having amine structure or imine structure, in which the composition satisfies [component (C)/component (B)‰¥1.0]. As a result, there is provided a room-temperature-curable organopolysiloxane composition that has good curability and storage stability even without containing an organotin compound or an organotitanium compound, has safety in view of toxicity to the human body and environment, and exhibits good rubber physical properties and adhesion after curing.
