Undusted pigments is a series of powdered mica and aluminum effect-pigments used to reach the effect of silver, gold, copper or pearl in PVC-plastisols, printing inks or in the other water-based or solvent systems. A specially developed pigment processing technology made it possible to avoid the problem of the pigments significant loss during mixing with the binder. The undusted effect-pigments have no “volatility” as the traditional powder pigments, own excellent dispersibility in the used system (binder).
