C.I.Pigment Black 28 (Copper Chromite Black Spinel )
CI # 77428          CAS # 68186-91-4

 C.I.Pigment Black 28 is a jet-black powder produced by high temperature calcination. This pigment has 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.
