Green 187B
CI Pigment Blue 36
Cobalt Chromite Blue-Green Spinel

A purified version of our standard Green. A rich greenish-blue powder produced by high temperature calcination followed by water treatment to remove soluble traces. This pigment has low residual solubles, good UV and visible opacity, is chemically inert, heat resistant, and stable toward ultraviolet light. It is non-bleeding and non-migratory. It has exceptional durability, 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.
