Abstract

There is prepared a homogeneous mixture of 95 to 30% carbon black and 5 to 70% resorcinol. The resorcinol preferably either has an average particle size of 0.10 to 0.4 0.40 mm or is broken down to that size. The product is employed in rubber mixture to improve the adhesion of rubber vulcanizates to metal, textile fibers, glass fibers, or their structures.
