Abstract: Described herein is a composite material including perfluoroalkoxy polymer powder, carbon black powder and a film-forming liquid, where the proportion by mass of the film-forming liquid is from 0.05% by weight to 1.0% by weight, the film-forming liquid at least partially wets the surfaces of the particles of the perfluoroalkoxy polymer powder, and the particles of the carbon black powder adhere to the film-forming liquid and/or the particles of the perfluoroalkoxy polymer powder. Also described herein are a production process for coating metallic surfaces, which uses the composite material as starting material, and further uses of the composite material.
