AC 5019 is a blackening process for Zn, Zamak, Zinc plates, Zinc coatings and dip galvanizing, which works at room temperature and can produce solid black coatings resistant up to 180 °C. For proper blackness, the thickness of the zinc coating should be at least 7.5 microns. Black coating can also serve as a subfloor for organic finishes such as lacquer and enamel. The coating is normally resistant to internal atmospheres and additional protection can be obtained by oiling, waxing or lacquering. The coating is not weather resistant.
AC 5019 Zn can be dull or shiny depending on the surface condition of the Zinc. Polishing the surface before making it black will result in a very glossy black coating. It should be covered with transparent lacquer for high gloss. Dull or matte finishes can be obtained by brushing the zinc surface or using abrasives such as wire or pumice stone.
