Cobalt Blue Pigment
Cobalt Blue namely: Thenard's Blue; Cobalt ultramarine; King's Blue cobalt Blue is an environmentally friendly, non-toxic inorganic pigment with high performance.
Excellent covering power, strong tinting power and dispersibility; Excellent outdoor light resistance, weather resistance and high temperature resistance; Good acid, alkali, solvent and chemical corrosion resistance; And has no infiltration, no migration; And it has good compatibility with most thermoplastic and thermosetting plastics. Also has the anti-infrared function, widely used in coil steel paint, engineering plastics, anti-counterfeiting paint and roof insulation paint.

Cobalt blue features
Cobalt blue crystal belongs to spinel structure, temperature resistance up to 1200-1400℃, which is beyond the reach of ordinary pigments. It also has excellent dispersion, light resistance, weather resistance and acid and alkaline resistance, chemical resistance.
The color is bright and pure with noble air. It is a very saturated blue pigment with a bright red hue;
Cobalt blue is a non-toxic pigment due to its manufacturing process and crystal structure, which does not precipitate free metal ions and has excellent acid and alkaline resistance. Comply with FDA standards.
With infrared reflection function, it can be used in military anti-counterfeiting coatings and roof insulation coatings or materials;
Disadvantages of cobalt blue: The raw material contains cobalt oxide or cobalt compounds, which is expensive and expensive to produce, so it cannot be widely used in common fields.
USES of cobalt blue
Application: 1. Coil coatings, high temperature coatings, engineering plastics, fluoroplastics, plastic toys, advanced art pigments and other fields.
2. Apply to color the fluorescent body in CRT of color TV. Nano cobalt blue pigment can also be used in high light transmittance paint of automobile lamps.
3.RPVC, polyolefin, engineering resin, fluorocarbon coatings, coatings for industrial coil steel industry and extrusion adhesive industry, as well as colored stone, cement building materials and other industries.
4. It conforms to THE European ROHS standard, The European EN71-3 standard, the American ASTM F963 standard and the Japanese SONY standard, and can be applied to the coloring of plastic products such as food packaging and containers, children's toys and tableware.
