Adhesive compositions.

摘要

Adhesive compositions are provided in which certain silane compounds are added as adhesion promoters to addition curing type compositions which comprise a diorganopolysiloxane containing alkenyl groups bonded to silicon atoms and an organohydrogen polysiloxane containing hydrogen atoms bonded to silicon atoms. The adhesion promoting silane compound is of the formula: <CHEM> wherein R<1> and R<2> are either hydrogen atoms or lower alkyl groups, R<3> and R<4> are preferably lower alkyl groups and a and n are integers from 0 to 2.
