Copper Chromite Black is a bluish black, They have 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 tint 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, it made more effectively dispersed in water-based coatings.
