Cobalt Blue/P.B.I.28 Application
1. Cobalt blue pigments are mainly used in high-temperature coatings, ceramics, enamels, glass coloring, high-temperature engineering plastics coloring, and as fine arts pigments. 2. Cobalt blue pigments can be used in general plastics, fluorocarbon plastics, toy plastics, food packaging plastics, printing ink, masterbatch, high performance industrial coatings, traffic printing paint, etc. 3. Advanced cobalt blue pigments have been applied to the coloring of fluorescent bodies in CRT picture tubes of color TV sets. With the development of nanotechnology, nanometer cobalt blue is also produced in foreign countries, which is used in automotive lamps with high transmittance. 4. Cobalt blue is used in RPVC, polyolefin, engineering resin, coatings and general industry, coiled steel and extruded adhesive paint, quartz particles, etc.
