Popular science knowledge: 2-black pigments for paints

4.
Copper chrome black

It is a metal oxide mixed-phase pigment with the characteristics of high temperature resistance, high weather resistance, environmental protection and non-toxicity.
It is mainly used for high temperature resistant coatings, high temperature resistant engineering plastic coloring, ceramics, enamel, glass coloring, and food contact plastic coloring.

5.
Iron chrome black

It is a metal oxide mixed phase pigment with excellent chemical resistance, outdoor durability, light resistance, high temperature resistance, environmental protection, non-toxic, no bleeding, no migration, and has a very good infrared reflection function.
It is suitable for almost all application fields such as plastics, paints and coatings.
Its color spectrum ranges from reddish brown to brownish black.

6.
Nigrosine

Nigrosine is the only black pigment among organic pigments, and it is also a widely used organic pigment.
Since generally black pigments are mostly inexpensive inorganic carbon black pigments, this solvent-based black pigment is not widely used in the coatings industry.

7.
Antimony sulfide

Antimony sulfide (Sb2S3) is a gray-black mineral pigment that shows green light, making it look like a plant in infrared photos, so its fine powder can be used as a camouflage paint.
