Abstract
This invention discloses an adhesive organopolysiloxane compositions which cure in the presence of addition reaction catalysts and adhere firmly to various materials when they harden comprising; PA1 (1) 100 parts by weight of an organopolysiloxane containing at least alkenyl groups bonded to silicon atoms in 1 molecule, PA1 (2) an organohydrogenpolysiloxane containing at least 3 hydrogen atoms bonded to silicon atoms in 1 molecule, in sufficient quantity to donate 0.5-10 hydrogen atoms bonded to silicon atoms to 1 alkenyl group in said 1st constituent, PA1 (3) 0.1-20 parts by weight of an organosilicone compound containing at least 1 hydrogen atom bonded to silicon atoms, at least 1 fluoroalkyl group or fluoroalkylether group bonded to silicon atoms via carbon atoms and at least 1 epoxy group and/or trialkoxysilyl group bonded to silicon atoms via carbon atoms in 1 molecule, and PA1 (4) platinum or a platinum compound in suitable quantity to act as a catalyst.
