- Light fastness: Light fastness rating is assessed on 1 to 8 Blue Wool scale where 1 = ‘Poor’ and 8 = ‘Excellent’.
- Heat Stability : Heat stability values given indicate the maximum temperature at which the pigment can be stoved for 10 min. on the full shade and in reductions without undergoing any significant change in shade.
- Oil absorption: The oil absorption is determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.
- Solvent bleeding: The bleeding in solvents is tested using the powder grades and the visual rating given on 1 to 5 Grey scale
where 1 = ‘Heavy bleeding’ and 5 = ‘No bleeding”

Frequently Asked Questions — PIGMENT RED 179
What primary applications does PIGMENT RED 179 (CAS 5521-31-3) excel in?
PIGMENT RED 179 (HP RED 26239) is primarily recommended for industrial coatings including high-grade original automotive OEM finishes and automotive refinishes, due to its excellent light and weather fastness. It is also widely used in plastics production, specifically in PVC plastisols, and is suitable for solvent-based and water-based paints. For plastic manufacturers, it demonstrates compatibility with a broad range of polymers such as PP, PE, PVC, ABS, PC, POM, PA, and PMMA, as well as technical plastics like PET and PBT.
How does PIGMENT RED 179 perform in demanding industrial coating systems?
PIGMENT RED 179 is engineered for high-grade automotive OEM finishes and refinishes, delivering outstanding light fastness and weather resistance. In solvent-based and water-based paints, the pigment provides strong acid fastness, making it a reliable choice for powder coatings and wood coatings. For ink manufacturers, it is equally effective in offset inks and both solvent-based and water-based ink systems, ensuring consistent performance across diverse coating and printing applications without compromising on stability.
Is PIGMENT RED 179 compatible with engineering plastics for masterbatch production?
Yes, PIGMENT RED 179 is fully recommended for high-temperature engineering plastics including PC, POM, PA, PET, PBT, and PMMA. It also processes well in polyolefins like PP and PE, as well as in PS/SAN, ABS, and various rubber/TPV, SBC, TPO, and TPU systems. This broad polymer compatibility allows masterbatch producers to use a single pigment grade across multiple plastic product lines while maintaining consistent heat stability and lightfastness.
What are the key technical specifications of PIGMENT RED 179 relevant to ink formulation?
PIGMENT RED 179 (CI 71130) has a chemical formula of C26H14N2O4 and is classified under EINECS 414-200-4. For ink formulators, its specific density and specific surface area data are critical for dispersion, while its heat stability and light fastness ratings make it ideal for high-durability printing inks. Although exact numerical values for heat stability (°C) and light fastness are maintained on the product datasheet, the pigment is proven in both offset and solvent/water-based ink vehicles for excellent bleeding resistance in xylene and methyl ethyl ketone.
How does PIGMENT RED 179 support batch consistency for high-volume plastic and coating production?
Every batch of PIGMENT RED 179 is tested for color strength, shade, dispersibility, and particle size against internal standards per ISO 9001 procedures. These documented results ensure batch-to-batch uniformity for critical applications, from automotive OEM paints to PVC plastisols. This rigorous quality control is essential for industrial coating manufacturers and plastic compounders who require consistent rheology and color development across large production runs.
