ROOM TEMPERATURE-CURABLE ORGANOPOLYSILOXANE COMPOSITION

摘要

A curable organopolysiloxane compsn. consists of (a) 100 wt.% of diorganopolysiloxane with hydroxy gp. at both terminal of molecular chain and viscosty of 1,000-1,000,000 cS at 25≦̸C C, (b) 1-20 wt.% of alkoxysilane or organosiloxane with three or more alkoxy gps., (c) 0.05-10 wt.% of organic silicon cpd. with one or more of (I) [R1=methyl or ethyl; Me= methyl; n= 0 or 1 , (d) 0.1-10 wt.% of (II) [Q= di-valent organic silicon gp.; R2=C1-3 alkyl R3=R2 or R2O!. The compsn. has an excellent self-adhesion to plastics.
