AC 5019 is a blackening process for Zn, Zamak, Zinc plates, Zinc coatings and dip galvanizing, which works at room temperature and can obtain durable black coatings up to 180 °C. For proper blackness, the thickness of the zinc coating must be at least 7.5 microns. Black coating can also form the basis for organic finishes such as lacquer and enamel. The coating is normally resistant to internal atmospheres and additional protection can be achieved by oiling, waxing or lacquering. The coating is not resistant to open air.
AC 5019 Zn can be dull or shiny depending on the surface condition of the Zinc. Polishing the surface before applying black results in a high-gloss black coating. It should be coated with transparent lacquer for high shine. Dull or matte finishes can be achieved by brushing the zinc surface or using abrasives such as wire or pumice stone.
