A coating agent, which comprises a cellulose derivative, an isocyanate group-containing 1,2-polybutadiene, a synthetic wax having a softening point of 100°-150° C., a fatty acid amide having a softening point of 60°-170° C., and graphite, can satisfy desired performances, when applied to rubbery elastomers, etc. such as prevention of sticking, adhesion and blocking, and improvement of abrasion resistance, and also can serve as a surface-treating agent for vulcanized rubber without peeling of coating films due to adhesion under high-temperature compression or friction-abrasion under high specific pressure.
