Pigment Red 48:1

Pigment Red 48:1 is red pigment with bright yellowish shade. PR48:1 is much yellower than PR57:1. It is mainly applied in gravure printing ink and plastics. In soft PVC, it has good migration resistance and has no frost. And in PE, its heat resistance can be 200-240℃/5min. It is also recommended for low end paint application with a light fastness of 5-6.

Product Details


The coloring strength of Pigment Red 48:1 is high. PR48:1 is good in solvent resistance, but its resistance to acid and alkali is not so good. Its light fastness and heat resistance is good.it is soluble in concentrated nitric acid and sulfuric acid, and will turn to brown red and purple red in the solution
