DCL Blue 30C591 is a dark blue powder produced by high-temperature calcinations. It has good UV and visible opacity, is chemically inert, heat-resistant, and stable to ultraviolet light. It is non-bleeding, non-migratory, and has exceptional durability and hiding power. It is generally used in applications requiring resistance to heat, light, and weather, and is compatible with most resin systems and polymers, being non-warping. Typical applications include liquid and powder coatings, inks, dispersions, concrete, plastics, and other uses requiring equivalent pigment chemistry.
