Copper Chromite Black, pigment balck 28 is a bluish black. It has excellent heat resistance, light resistance, acid resistance and alkali resistance in common. As a result of our own advanced manufacturing technique and strict control, which endow it with high tinting strength and good dispersibility. With the development of water-based coating, we exploited w-type copper chromite black to water based coating, after special water borne surface treatment, to be more effectively dispersed in water-based coatings.
