Abstract

Liquid adhesion-promoting compositions for cohesively bonding organosiloxane materials to organic polymers comprise (A) a copolymer derived from at least one ethylenically unsaturated organic compound and at least one silane containing an ethylenically unsaturated organic group and at least two silicon-bonded hydrolyzable groups per molecule, (B) an organohydrogensiloxane, (C) an aminosilane containing at least 2 alkoxy or other hydrolyzable groups, and (D) an amount of an organic liquid sufficient to solubilize ingredients A, B and C of said composition and achieve the desired viscosity.
