Copper chromium black is a blue-phase black pigment calcined at high temperatures. It possesses excellent chemical resistance, outdoor durability, lightfastness, thermal stability, and features of non-bleeding and non-migrating. It is widely used in fields with high requirements for heat resistance, weather resistance, and light resistance, and is compatible with most resins or polymers.
