Pigment Yellow 180

Pigment Yellow 180 is an organic pigment with many advanced characteristics. It is often applied in PVC, engineering plastics, and polycarbonate. In the production process, the surface treatment and particle size of Pigment Yellow 180 have much influence on its performance. With surface modification on Pigment Yellow 180 and adding certain amount of dispersants or emulsifier, the property of Pigment Yellow 180 can be greatly improved. It is greenish yellow pigment and is the only disazo pigment in the benzimidazolone yellow pigments. Pigment Yellow 180 is high in tinting strength and is mainly applied in coloring of palstics, powder coating, inks, rubber, and coloring of pulp of synthetic fibers.

Pigment Yellow 180 is greenish shade yellow powder and has semi opaque and transparent type. It is suitable for the coloring of plastics and its heat stability in HDPE is 290 degree. It has excellent migration resistance, and is widely applied in ABS and PVC products. Its good dispersion and stable flocculation makes it suitable for high end printing ink, such as metal decorative ink and water based package ink. PY180 has good performance in acid, alkali and solvent condition.
