    摘要: A coating composition comprising (A) a urethane polymer having at least one aliphatic unsaturated hydrocarbon group on a side chain in a molecule, (B) an organohydrogenpolysiloxane having at least two hydrosilyl groups in a molecule, and (C) a hydrosilylation catalyst firmly bonds to surfaces of various substrates, especially silicone rubber substrates, without a need for pre-treatment and readily forms thereon a surface protective layer having wear resistance. A silicone rubber member in which a silicone rubber substrate is coated on its surface with the inventive coating composition is endowed on the surface with wear resistance and is useful as silicone rubber key pads and silicone rubber rolls.

    摘要: The present invention provides polydiorganosiloxane oligourea segmented copolymers. The copolymers contain soft polydiorganosiloxane units, hard segments that are diisocyanate residues, the polydiorganosiloxane units and diisocyanate residues being connected by urea linkages, and terminal groups that are nonreactive, reactive under free radical or moisture cure conditions, or amines. The invention also provides methods of preparing the copolymers.
