Pigment Orange PO13 - Bright Orange for Inks, Paints, and Coatings

Pigment Orange PO13 delivers uncompromised brilliance and durability for premium coatings, inks, and industrial finishes. As a benzimidazolone-based organic pigment, it combines intense reddish-orange hues (CIE Lab*: L* 52±2, a* 48±1, b* 65±2) with exceptional lightfastness and chemical resistance. Engineered for automotive refinish systems, architectural coatings, and packaging inks, PO13 outperforms conventional oranges in chromatic purity and processing stability.
