Pigment Red 48:2
Pigment Red 48:2 is a red pigment with bright bluish shade. Its color shade is much bluer than Pigment Red 48:1 and Pigment Red 48:4. It has both transparent and semi-transparent type. PR48:2 can be used as standard color in the application of gravure printing ink. The main application is NC based package printing ink, as it will turn thick in water based ink. In soft PVC, it doesn’t have color penetrating. And its heat resistance in HDPE is 230℃/5min, and is often used in the coloring of LDPE. PR48:2 has better light fastness than PR48:1.
Product Details
Features
The color strength of Pigment Red 48:2 is high and its dispersibility is good. It has good heat resistance and good resistance in the system of aliphatic and aromatic hydrocarbons, but not good in acid and alkali resistance. PR48:2 is purple red in sulfuric acid and after diluted it will be blue red precipitation
