  • Moisture-curable hot melt silicone adhesive compositions including an alkoxy-functional siloxane reactive resin
    Patent number: 10370572
    Abstract: A moisture-curable silicone adhesive composition is provided that comprises (A) a reactive resin, (B) a reactive polymer, (C) a moisture cure catalyst, and (D) a crosslinker resin. The reactive resin (A) comprises the reaction product of a reaction of an alkenyl-functional siloxane resin comprising R3SiO1/2 units and SiO4/2 units and an alkoxysilane-functional organosiloxane compound having at least one silicon-bonded hydrogen atom in the presence of a hydrosilylation catalyst. The reactive polymer (B) comprises the reaction product of a reaction of an alkoxysilane-functional organosiloxane compound having at least one silicon-bonded hydrogen atom and a polyorganosiloxane having an average, per molecule, of at least 2 aliphatically unsaturated organic groups in the presence of a hydrosilylation catalyst.
