What are the characteristics of organic pigments for coatings?

2021-08-26   Pageview:310

Organic pigments have higher coloring strength, brighter colors and complete chromatography. In recent years, we have been developing new heterocyclic yellow, orange, red and purple spectrum pigment varieties, and have the application performance matching with phthalocyanine blue and green pigments. It is not only used for printing ink and plastic coloring, but also widely used for metal surface coating and architectural coating coloring.

The organic pigments commonly used in coatings include classical pigments and high-grade pigments to meet the requirements of light resistance and solvent resistance. The main application areas of coatings are distinguished, including automotive paints, architectural and decorative paints, industrial paints, powder coatings, coil steel coatings, etc.

 

 

 

 

 

 

 

 

 

In the early days, the pigments used for coloring low-grade paints mostly belong to insoluble azo pigments, with simple process, low cost and good application performance, for example, Hansa system yellow (C.I. pigment yellow 1, pigment yellow 3 and pigment yellow 5, etc.), orange spectrum (C.I. pigment orange 5), red spectrum: toluidine red (C.I. pigment red 3), toluidine violet red (C.I. pigment red 13); blue and green spectrum are For phthalocyanine blue and phthalocyanine green and other varieties.
