Complex Inorganic color Pigments
Cobalt Violet (PB 73)

Cobalt Violet is an inorganic violet pigment primarily composed of a compound of cobalt oxide and aluminum oxide, characterized by its soft and unique violet hue with excellent weather resistance, heat resistance, and chemical corrosion resistance. It features a uniform particle distribution, providing good opacity and tinting strength, and maintains color stability and durability under UV exposure and in various harsh conditions without fading or migrating. Additionally, it is non-toxic and environmentally friendly, making it a high-quality violet pigment.
