Abstract
Proposed is a novel organopolysiloxane composition in the form of a water-base emulsion suitable for use as a surface-coating agent on rubber articles such as automobile parts to impart excellent smoothness of the surface, abrasion resistance, adhesion to the rubber surface and so on. The composition comprises: (a) an organopolysiloxane having a viscosity of at least 10000 centipoise at 25.degree. C. and having a molecular structure consisting of the difunctional siloxane units and the trifunctional siloxane units terminated at each molecular chain end with a hydroxy group, in the form of an aqueous emulsion; (b) a hydrolysis-condensation product of an epoxy group-containing dialkoxy silane in the form of an aqueous emulsion; (c) a water-soluble organic amino compound having at least two amino groups in a molecule and containing no silicon atom; and (d) silicone rubber particles in the form of an aqueous dispersion, each in a specified weight proportion.
