Black 30C941
CI Pigment Brown 29
Chromium Iron Oxide

A black powder produced by high temperature calcinations. This pigment has a blue-shade masstone color while having high near-IR reflectivity. It is chemically inert, heat resistant, and stable to ultraviolet light. It is non-bleeding, non-migratory and non-warping. It has exceptional durability and hiding power, and is generally used in applications where resistance to heat, light, and weather are needed. It is compatible with most resin systems, polymers and binders. Typical applications (non inclusive) are liquid and powder coatings, inks, dispersions, concrete, plastics, and other applications where equivalent pigment chemistry is used. This product is very easily dispersible and does not need small media milling for Dispersion. It can simply be processed using most laboratory and production high-shear mixing equipment to achieve full dispersion.
