Pigment Red 179

Pigment Red 179 is used in the coloring of automotive coating and refinish, polyvinyl chloride plastics, and fibers. Among the perylene red pigment series, PR179 is one of the pigment with highest business value. For the automotive coating and refinish, it can be mixed together with other organic or inorganic pigment to extend the hue to yellow-red area and meet more application requirements. It also has excellent weather and light fastness, even better than substituted quinacridones. Its heat stability can reach 180-200℃.

Product Details


Pigment Red 179 is an opaque and dark red powder with high performance. It has the biggest consumption among perylene pigments, and is applied in the formulation of automotive coating. It has high coloring strength and excellent heat resistance in PO and PVC. It has good stability and is suitable for the EDPM,PP,PA and PET fiber.
