<P>PROBLEM TO BE SOLVED: To provide a dealcoholizing one-pack type ambient temperature-curing organopolysiloxane composition which is low in transmission oil foaming and gives a seal of excellent oil resistance. <P>SOLUTION: The low-foaming ambient temperature-curing organopolysiloxane composition includes the following components (A)-(E): (A) 100 pts.mass diorganopolysiloxane having at least two silanol groups or an alkoxy group in the molecule and a degree of polymerization of not smaller than 10, (B) 10-300 pts.mass inorganic filler, (C) 1-30 pts.mass alkoxy silane represented by general formula (7): R<SP>1</SP><SB>4-n</SB>Si(OR)<SB>n</SB>, its partial hydrolysate or their combination (wherein R is a mutually independently 1-4C alkyl group, R<SP>1</SP>is a mutually independent substituted or unsubstituted 1-20C monovalent group and n is an integer of 2-4), (D) 0.01-15 pts.mass curing catalyst and (E) 0.05-15 pts.mass silane coupling agent. <P>COPYRIGHT: (C)2010,JPO&INPIT |
