Pigment yellow 13

Pigment Yellow 13 (CAS 5102-83-0), also known as Diarylide Yellow and abbreviated as PY13, is a high-performance organic pigment used to deliver bright, opaque yellow coloration across a broad range of industrial substrates. Commercially available under trade names such as Monolite Yellow GL and Helio Fast Yellow GRF, it is a benchmark yellow pigment valued for its strong tinting strength and cost-effective performance in demanding production environments.

In printing inks, PY13 is a standard choice for offset and flexographic formulations where high color strength and good transparency are required for process yellow applications. Plastic compounders incorporate it into polyolefins, PVC, and engineering resins to achieve consistent yellow shades in finished consumer and industrial goods.

Coatings manufacturers use it in industrial and decorative paints where opacity and batch-to-batch color consistency are critical for high-volume manufacturing. In paper and textile applications, it delivers uniform surface coloration in coated papers and pigment-printed fabrics, ensuring a high-quality finish across various materials.

PY13 is supplied as a dry powder, with press cake forms available from select manufacturers for direct dispersion into liquid systems. It is offered in technical and industrial grades. Specific formulations are optimized for either solvent-based or water-based systems. Particle size and surface treatment variants are available to meet the dispersion requirements of different end-use applications.
