DCL Black 1 is a jet-black powder produced by high temperature calcination that has good UV and visible opacity, is chemically inert, heat-resistant, and stable to ultraviolet light. It is non-bleeding and non-migratory, has exceptional durability and hiding power, and is compatible with most resin systems and polymers. It is also non-warping and is typically used in applications such as liquid and powder coatings, inks, dispersions, and plastics, where resistance to heat, light, and weather are needed.
