Brown 30C888
CI Pigment Brown 33
Zinc Iron Chromite Brown Spinel

A reddish brown powder produced by high temperature calcination. This pigment has excellent 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, an is generally used in applications where resistance heat, light, and weather are needed. It is compatible with most resin systems and polymers, and is non-warping. Typical applications (non inclusive) are coatings and other applications where equivalent pigment chemistry is used.
