PURPOSE: To obtain a curable composition which is prepared by incorporating a specified quantity of isocyanulate, etc., into α,ω-dihydroxy diorganopolysiloxane polymer, does not contain a compound having a primary or secondary amine functional group, is stable in storage in the absence of water, and can be converted into an adhesive elastomer in the presence of water. n CONSTITUTION: A composition which is prepared by incorporating (B) 0.5-20 pts.wt. curing agent containing ketiminoxysilane, (C) 0.001-10 pts.wt. isocyanulate of formula II [wherein W is a monovalent hydrocarbon of formula III ((n) is 1-12)], (D) 5-250 pts.wt. inorganic filler (e.g.: silica obtained by pyrolysis, etc.), and (E) 0.0004-3 pts.wt. curing catalyst of a metal into (A) 100 pts.wt. α,ω-dihydroxy diorganopolysiloxane polymer which consists of a diorganosiloxane unit of formula I (wherein T is a 1-10 hydrocarbon, and at least 50% of T is methyl) and has viscosity of 700-1×10 6 Pa and does not contain a compound containing a primary or secondary amine functional group at all. n COPYRIGHT: (C)1991,JPO |
