Cobalt Blue (PB 36)

Cobalt Blue is an inorganic blue pigment primarily composed of a compound of cobalt oxide and aluminum oxide, known for its vivid and stable blue hue, along with excellent weather resistance, heat resistance, and chemical corrosion resistance. It features a uniform particle distribution, providing outstanding opacity and tinting strength, and maintains color stability and durability under UV exposure and various harsh conditions without fading or migrating. Additionally, it is non-toxic and environmentally friendly, making it a superior quality blue pigment.
