ADHESION-PROVIDING AGENT FOR PHOTOSETTING ORGANOPOLYSILOXANE COMPOSITION AND PHOTOSETTING ORGANOPOLYSILOXANE COMPOSITION

摘要

PURPOSE: To obtain the subject adhesion-providing agent consisting of a specific organosilicon compound and an organometallic compound and capable of rapidly curing by irradiation of light such as ultraviolet rays and providing a cured product excellent in adhesion and retention thereof. ;CONSTITUTION: The objective adhesion-providing agent is obtained by blending (A) 100 pts.wt. organosilicon compound containing 1-20mol% unit of formula I, 20-80mol% unit of formula II and 20-80mol% unit of formula III [R¹ is alkenyl; R² is alkyl, alkoxyalkyl, etc.; R³ is 1-4C alkoxy; (a) and (b) are 0 or 1; (c) is 0-2, with the proviso that (b+c) is 1 or 2; (d) is 0 or 1; (e) is 0-3, with the proviso that (d+e) is 1-3; furthermore, R¹ content to total organic group bound to silicon atom in the molecule is ≥2mol% and R³ content is ≥5mol%] with (B) 0.005-2000 pts.wt. organometallic compound selected from a group consisting of an organotitanium compound (e.g. tetrabutoxytitanium), an organozirconium compound [e.g. tetrakis (10-undecyclic acid) zirconium[ and an organoaluminum compound (e.g. trimethoxyaluminum).;COPYRIGHT: (C)1994,JPO&Japio
