The invention concerns a method of coating preferably electrically non-conducting surfaces with preferably electrically conducting finely particulate materials by dipping the article to be coated into the following baths in succession: a) an aqueous solution of polymers (pre-dip solution), b) an aqueous dispersion of the finely particulate material, the dispersion also containing surfactants to prevent sedimentation and a salt to ensure the controlled destabilization of the dispersion. Coating with electrically conducting particles, such as graphite or carbon black, can be carried out in preparation for the galvanic deposition of a metal. |
