Chemical Properties

Pigment Orange 64 GP is a bright reddish orange powder, belonging to the benzimidazolone group of pigments. It has excellent sunlight resistance, heat resistance, solvent resistance, acid resistance and alkali resistance. In plastics can withstand 300 ℃ / 5min, just with the temperature increases, the tone of yellowish light, does not affect the crystallinity of the polymer, does not produce size deformation; in the plastic PVC has good migration resistance. In metal decorative printing ink, heat-resistant stability of 200 ℃.

Uses

Pigment orange 64 is a pyrazolone dye commonly used in industry.
