Novel organosilicon compound and a room temperature curable organopolysiloxane composition containing the same |
摘要 |
The invention discloses a novel cyclic organopolysiloxane compound having one or more of 3,3,3-trifluoropropyl groups and one or more of alkenyloxy groups, e.g. isopropenyloxy group of the formula -O-C(CH3)=CH2, each directly bonded to the silicon atom in a molecule. This novel organopolysiloxane compound is useful as a crosslinking agent for a hydroxy-terminated diorganopolysiloxane and a formulation of a room temperature curable organopolysiloxane composition capable of giving a rubbery elastomer by curing is proposed comprising, each in a limited proportion, (a) a hydroxy-terminated diorganopolysiloxane, (b) the above disclosed novel cyclic organopolysiloxane having 2 or 3 alkenyloxy groups, (c) a second cyclic organopolysiloxane having 2 or 3 alkenyloxy groups each directly bonded to the silicon atom in a molecule and (d) a guanidino-containing organosilicon compound, e.g. 3-(tetramethylguanidino)propyl trimethyl silane, as a curing accelerator. This room temperature curable composition exhibits excellent curability and free from the problem of the formation of noxious condensation products as in the conventional RTV silicone rubber compositions.
