Abstract

A surface-treating agent for vulcanized rubber, comprising, based on 100 parts by weight, as solid matters, of isocyanate group-containing 1,2-polybutadiene, an organic solvent solution containing 10 to 160 parts by weight of fluororesin particles and 2.5 to 20 parts by weight of a perfluoroalkyl group-containing oligomer-based, fluorine-containing surfactant as a dispersant. The surface-treating agent for vulcanized rubber improves the solution stability of the organic solvent solution, improves the further hardness of the entire coating film formed from the surface-treating agent, abrasion resistance, and product torque evaluation, and is effectively used as, for example, a coating agent for seal lip parts of oil seals.
