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.

Silver White pigments have excellent silver luster effect with the applicability and stability, which can bring you the best pearlescent effect.
Two available types of silver white effects are anatase and rutile are optional, the rutile has better weather resistance. Depending on the particle size, effects ranging from silky smooth to glitter are possible.
Interference pigments are similar to rainbow interference color, it creates gold, orange, red, violet, blue and green in turn, and possessing high color chroma. It does not contain any organic pigment without color faded and transfer.
Due to the interference dual-colored effect, when combining with organic pigment, the grounding should be taken into considered. In this way, it will bring interference attractive effect.
Gold luster pigments consisted of mica coated with titanium dioxide and iron oxide, depending on accurately controlling the thickness of the coat, creating various of gold luster.
They can be formulated with each other when a special gold is needed, selecting difference type of gold and accurately controlling the proportion, hereby the best gold effect will be achieved.
Besides, it conquers the disadvantage of color change of conventional cupreous gold powder.
This series can be used alone or formulated with other transparent pigment, it make the color be rich and colorful and the final products be more attractive.
Metallic luster effect pigments are consisting of mica coated with Fe2O3, it creates different color also depending on controlling the thickness of Fe2O3, they simulate the shine of metal. Abundant of color, better coverage performance and stabile physical and chemical.
