Cobalt blue is a cobalt aluminum alloy with an anti-spinel structure and resistant to temperatures up to 1000C. It has a bright hue and a sky blue color. It has a bright, sky blue color, high dispersibility, high weather resistance, high alkali resistance and solvent resistance. Its composition is environmentally friendly and non-toxic because its manufacturing process and crystal structure do not precipitate metal ions. It has good visible and UV opacity and is chemically stable in UV light, so it has excellent hiding power and durability. Cobalt Blue is compatible with most resin systems and polymers and is non-warping, with a very large specific surface area, low resin requirements and high luminosity. Therefore its typical applications are high-end liquid and powder coatings, inks, dispersions, concrete, plastics and masterbatches.
