Pigment Red 170

Pigment Red 170 is a new pigment which is introduced to the market recently. It has a higher light resistance of 0.5-1, and is less sensitive to sterilization and varnish, etc. It has two crystal types; the transparent type is light and blue red, and its light fastness can reach level 5-6; the fastness of the non-transparent type can reach level 7. PR170 is mainly used for water-based printing inks, solvent-based printing inks, printing and dyeing of coatings and  fabrics.

Product Details


Pigment Red 170 is brilliant red powder with bluish shade, and its bluish shade is much bluer than PR210. It is semi-transparent, and has good light and weather fastness. With excellent coloring strength, it needs only 0.22% to make a formulation with 1% titanium dioxide in coloring of HDPE products
