  • PVD METAL EFFECT PIGMENT POWDER
    Publication number: 20170306159
    Abstract: The invention relates to powder made of coated PVD metal effect pigment, highly concentrated suspensions of coated PVD metal effect pigment as well as the use thereof in powder lacquers and masterbatches. The powder according to the invention made of coated PVD metal effect pigments is characterized by a very good redispersibility and is outstandingly suitable in particular for the preparation of highly concentrated suspensions. Furthermore, it is very free flowing, substantially agglomerate-free and results in coatings with excellent metallic gloss.
