Black 30C940
CI Pigment Green 17
Chromium Iron Oxide

A black powder produced by high temperature calcinations. This pigment has high infrared reflection, good UV and visible opacity, is chemically inert, heat resistant, and stable to ultraviolet light. It is non-bleeding and non-migratory. 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 and polymers, and is non-warping. 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, does not need grinding for dispersion and can simply be stirred in using most laboratory and production equipment to achieve full dispersion.
