Cobalt Blue Properties
EMPEROR Cobalt Blue is also named king blue, thenard blue or cobalt ultramarine, is a very bright blue. Cobalt blue is a mixed metal oxide pigment of spinel pattern. It has excellent heat resistance, light-fastness, acid resistance, alkali resistance and non-toxic, so it can be used in the area which required high heat resistance, excellent color stability and ageing resistance.
It can be use for fluorocarbon coatings, heat resistant coatings, plastics, ceramics, grass and artists' colors.
