Black 444
CI Pigment Black 26
Manganese Ferrite Black Spinel

A very jet-black 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, and is generally used in applications where the absence of chromium is desired, and resistance to heat, light, and weather are needed. It is compatible with most resin systems and polymers, and is non-warping.
