Pigment Red 242 has a yellowish red or large red phase, and is excellent in solvent resistance and acid / alkaline resistance. It is mainly used for coloring of plastics such as PVC, PS, ABS, and polyolefins. It is heat-resistant to 300 ° C (1 / 3SD) in HDPE, but it affects dimensional deformation. It is suitable for the coloring of raw pulp of polypropylene and resistance to migration in soft PVC. It has medium tinting strength; it is also recommended for coatings, automotive coatings, anti-glazing paints, and heat-resistant 180 ° C; for high-end printing inks, such as PVC film and metal decorative printing inks, laminated plastic films, etc.
