CURABLE RESIN COMPOSITION

摘要

PURPOSE:To improve the curing properties in the deep together with heat resistance and weathering properties by compounding a specific polyoxytetramethylene glycol polymer, a silanol group-contg. silicone compd. and a silanol condensation catalyst. CONSTITUTION:A polyoxytetramethylene glycol polymer (A) with a number- average MW of 500-30000, having a hydroxyl or hydrolyzable group attached to Si and at least one Si-contg. group capable of crosslinking by forming a siloxane linkage (e.g. formula I), a silicone compd. (B) having at least two silanol groups of formulae II to VI (wherein a and b are each 0-50; c+d is 1-50; Me is methyl; and Ph is phenyl) in such an amt. that the number of hydroxyl groups attached to Si is 0.1-8 per hydroxyl or hydrolyzable group in component A, and a silanol condensation catalyst (C) (e.g. tetrabutyl titanate) in an amt. of 0.1-20 pts.wt. per 100 pts.wt. component A are compounded.
