Related Information

Pigment Red 208 gives neutral red, hue color is 17.9 degrees (1 / 3SD, HDPE), and has excellent resistance to solvents and chemicals, and performance. It is mainly used for coloring of plastic raw paste and packaging printing ink. It does not migrate in soft PVC. It has a light resistance of 6-7 (1 / 3SD) and a heat resistance of 200 ° C. It is brown with CI Pigment Yellow 83 or carbon black. Polyacrylonitrile dope coloring, natural light resistance is grade 7; used for acetate fiber and polyurethane foam plastic dope coloring; it can also be used for packaging printing ink, its solvent resistance, sterilization resistance is good, but due to light resistance, weather resistance The degree of limitation has limited its use in general coatings.
Mainly used for plastic coloring.
