Pigment orange 13

Pigment Orange 13 (CAS 3520-72-7), commonly referenced as PO 13, is a disazo organic pigment delivering strong orange coloration with good heat stability and chemical resistance across industrial substrates. It is a cost-effective colorant used in high-volume manufacturing where consistent hue and processing durability are priorities. In plastics and polymers, it provides bright orange coloration in polyolefins and PVC.

Engineering resins benefit from this pigment where batch-to-batch color consistency is critical for compounders and masterbatch producers. Coatings formulators incorporate it into industrial paints and architectural finishes. It is also used in primers where opacity and lightfastness at moderate performance tiers are acceptable. Printing ink manufacturers rely on this pigment for packaging inks, particularly flexographic and offset applications.

Vivid orange tones are required on paper and board substrates for various commercial uses. In textile and leather processing, it is applied in pigment printing pastes and surface dyeing formulations. These applications target orange shades on synthetic and natural fiber goods. The product is supplied as a dry powder, typically in fine-milled form suited for dispersion into liquid systems or dry blending.

Technical grade is the standard commercial offering, with product specifications commonly defined by tinting strength, moisture content, and oil absorption values for industrial quality control. Packaging is available in bags and drums scaled to industrial procurement volumes. This ensures efficient handling and storage for large-scale manufacturing facilities requiring consistent pigment supplies.
