CURABLE ORGANOPOLYSILOXANE COMPOSITIONS

摘要

Organopolysiloxane compositions which are curable to elastomers via an addition reaction of unsaturated bonds to silicon-bonded hydrogen atoms in the presence of a group VIII metal catalyst have improved adhesion, without inhibiting their curing, by incorporating an organosilicon compound of the general formula (RO)cR3-cSiO(R2SiO)x(R'RSiO)y(R"RSiO)zSiR3-c(OR)c wherein R is a hydrocarbon, R' has olefinic unsaturation and at least 6 carbon atoms, R" contains an epoxy group and x, y and z are at least 1, z being 2 if c is O.
