2. Pigment properties

Shandong Caizhiyuan Pigment Technology: Cobalt Blue (C.I. Pigment Blue 28) is a bright and pure reddish blue pigment with saturated hue, excellent hiding power, tinting strength, dispersibility, light fastness, weather resistance, acid and alkali resistance, chemical resistance Characteristic and other characteristics, cobalt blue is an environmentally protection pigment, has infrared reflection function, and is widely used.

3. Pigment Properties

A. The cobalt blue crystal belongs to the spinel structure, and the temperature resistance reaches 1200-1400 ℃, which is beyond the reach of ordinary pigments. It also has excellent dispersibility, light resistance, weather resistance, acid and alkali resistance, and chemical resistance.

B. The color is bright and pure, showing a noble atmosphere. It is a very saturated blue pigment with a distinct red hue;

C. Because of its manufacturing process and crystal structure, cobalt blue does not precipitate free metal ions and has excellent acid and alkali resistance. It is an environmentally protection pigment. Meets US FDA standards.

D. With infrared reflection function, it can be applied to military anti-counterfeiting coatings and roof thermal insulation coatings or materials;

E. Disadvantages of cobalt blue: The raw materials contain cobalt oxide or cobalt compounds, which are expensive and have high production costs, so they cannot be widely used in ordinary fields.

4. Application areas

Cobalt blue is mainly used for the coloring of anti-counterfeiting coatings, roof thermal insulation coatings, coil coatings, high temperature coatings, engineering plastics, fluoroplastics, plastic toys, advanced art pigments and other products.

A. Coil coatings, high temperature coatings, engineering plastics, fluoroplastics, plastic toys, art pigments and other fields.

B. Applied to the coloring of phosphors in color TV CRT picture tubes. Nano cobalt blue pigment can also be used in automotive lighting coatings with high light transmittance

C. RPVC, polyolefin, engineering resin, fluorocarbon coatings and coatings for industrial coil steel industry and extrusion glue industry, as well as colored stone, cement building materials and other industries.

D. In line with EU ROHS standard, EU EN71-3 standard, American ASTM F963 standard and Japanese SONY standard, it can be used in the coloring of food packaging and containers, children's toys, tableware and other plastic products.

5. Product packaging
