International ClassB32B 013/12Foreign Application Priority Data1997-07-30 JPAbstractAn organopolysiloxane composition for surface treatment comprising (A) a reaction product of (1) a silane and/or a siloxane each having a substituted or unsubstituted amino group bonded to the silicon atom via at least one carbon atom and also having an alkoxy group bonded to the silicon atom and (2) a silane and/or a siloxane each having a monovalent hydrocarbon group bonded to the silicon atom, the hydrocarbon group being substituted with an epoxy-containing group, and an alkoxy group bonded to the silicon atom and (B) a specific organopolysiloxane containing an amino group. The composition provides a non-sticky, water-repellent and slippery film on a substrate, especially an EPDM rubber sheet and EPDM molded sponge, with markedly improved adhesion.Field of SearchMaterial contains a Group IVA metal atomMaterial contains a heavy metal atom Material contains a Group VIII metal atom Material is a nitrogen-containing compound With silicon reactant containing a single silicon atom Silicon reactant contains two or more silicon atoms Silicon reactant contains an amine nitrogen atom As siloxane, silicone or silane Of addition polymer from unsaturated monomers Next to addition polymer from unsaturated monomers, or aldehyde or ketone condensation product | |
