These metallic pigments are flat thin particles of polished metal made from mixtures of copper, zinc, tin, and antimony. Red, green, blue and amaranth shades are produced by adding dyes. Copper and aluminum powders are made from pure copper and pure aluminum. They are used for decorative effects with lacquers and varnishes. One to two pounds per gallon of vehicle are necessary to produce good coatings. Mix only enough for the job at hand as gelation may occur on prolonged standing. After mixing, the vehicle can be brushed or sprayed. The powder should be mixed with the thinner first to prevent lumping then the vehicle is added. A color card is available upon request.
