THIS CHAPTER IS BASED ON THE CONTENTS OF THE 14th edition. Careful consideration has been given to the addition of new information, test methods, and technology, thus providing the most up-to-date information available on metallic pigments. Metallic pigments, including aluminum zinc, gold, bronze, nickel, and stainless steel, provide the paint and coatings industry with a variety of aesthetic and functional properties. These pigments, either in flake or powder form, contribute to the metallic effects associated with automotive topcoats; general industrial finishes; silver, gold, and copper finishes; metallic ink systems; and many of the high-performance primers for coatings systems. In addition to providing metallic and polychromatic effects, they provide functional anticorrosive benefits.
