Abstract

A curable organopolysiloxane composition comprising (A) an organopolysiloxane having at least two alkenyl groups and a viscosity of 100 to 200,000 cs, (B) a specific organopolysiloxane having an alkoxysilyl group, (C) an organohydrogen polysiloxane having at least two hydrogen atoms attached to silicon atoms, and (D) an addition reaction catalyst is improved in adhesion. It cures to substrates of metals, glass, rubber and plastics to form a firm bond even in low temperature or brief high temperature curing conditions.
