2. Pigment properties

Shandong Caizhiyuan Pigment Technology: Copper chrome black (C.I. Pigment Black 28) is a black powder with extremely deep blackness and blue phase. It is environmentally protection, non-toxic, high temperature resistance, light resistance, weather resistance, acid and alkali resistance, solvent resistance, non-migration, easy to disperse and so on. Because of its excellent properties, copper chrome black has excellent applicability and versatility in various products, and is widely used in various coatings (such as exterior wall coatings, architectural coatings, automotive coatings, road marking coatings, water-based coatings, anti-ultraviolet coatings , powder coatings and high temperature coatings, etc.), color inks, high temperature plastics (such as engineering plastics, color masterbatch, etc.), building materials, colored glass, ceramics, enamel and other fields.

3. Application areas

Copper chrome black is mainly used in fields with high requirements for high temperature thermal stability and chemical inertness, such as: external high-durability industrial coil coatings; industrial coatings with oxidation resistance, reduction resistance and good chemical inertness; various barbecue grills and high temperature resistant coatings used in wood-burning stoves; high temperature resistant plastics and plastics with higher requirements for resistance.

In addition, copper chrome black is used as a toner in vinyl siding and paint, and it is incorporated into white pigments to prevent yellowing of white products. Can also be used to formulate neutral grays and various colors suitable for residential coatings
