Product Description of Pigment Red 48:2:

Compared with C.I. Pigment Red 48:1, 48:4, the pigment shows blue light, and the red has a blue-red hue and can be used as the standard color of gravure printing ink, but it is 57:1 more yellowish than pigment red. Mainly used for printing ink NC-type packaging printing ink, thickening in water-based printing ink; soft PVC coloring does not bleed, heat-resistant 230℃/5min in HDPE, widely used for LDPE coloring, more light-resistant than PR48:1 , It can also be used for the coloring of PP puree.It is mainly used for the coloring of ink, plastic, rubber, paint and cultural and educational supplies.
