KW® Pearlescent Pigments
KW® series are classic effect pigments, which consists of treated natural mica flakes coated with a thin layer of metal oxide, such as titanium dioxide or/and iron oxide. Through a combination of transparency, refraction, multiple reflections, particle size and coating thickness, a wide variety of color effects are produced. These color effects are found elsewhere only in nature - silver white, interference and metallic luster effects.
KW® series present excellent compatibility with all kinds of transparent and translucent systems, and also have very good dispersibility, light fastness, acid & alkali resistance and thermal stability etc. KW® series are non-migration, non-fading, non-toxic, non-conductive, non-flammable and environmentally safe. These unique properties make KW® pearlescent pigments widely applied in plastics, resins, paints and printing.
