Description

Pigment Orange 64 (CAS 72102-84-2) is a high-performance azo-benzimidazolone organic pigment delivering strong orange coloration with superior heat stability and lightfastness. It is engineered for demanding industrial colorant applications where durability under processing stress is a primary sourcing consideration for manufacturers and chemical distributors.

In plastics and polymer compounding, this pigment withstands high processing temperatures, making it suitable for engineering resins and masterbatch production across various sectors. Printing ink formulators select it for packaging applications requiring sharp, clean orange hues with resistance to migration and bleed during the manufacturing and storage process.

Automotive coatings benefit from its weathering resistance, supporting OEM and refinish coating systems where long-term color retention is critical for the final product appearance. Textile and leather dyeing operations use it where conventional azo pigments lack the thermal and fastness performance required by rigorous industrial end-product specifications.

The product is supplied as a dry powder, typically in fine-milled form to support dispersion in solvent-borne, water-borne, and UV-curable systems for diverse chemical formulations. It is available in standard commercial grades and in surface-treated variants optimized for specific binder systems. Packaging is commonly offered in fiber drums or bags.
