Pigment red 149

Pigment Red 149 (CAS 4948-15-6) is a high-performance perylene pigment delivering deep, bluish-red shades with outstanding heat stability and lightfastness. It belongs to the perylene diimide class, a group recognized by formulators for durability in demanding colorant applications.

In plastics, it withstands processing temperatures required for engineering polymers, making it a reliable choice for coloring polyolefins, PVC, and high-temperature thermoplastics without shade shift. This stability ensures consistent color quality during manufacturing.

Coatings formulators select it for automotive and industrial finishes where long-term exterior durability and resistance to weathering are critical performance requirements. It maintains its integrity even when exposed to harsh environmental conditions over time.

Printing ink manufacturers use it in high-quality packaging inks where color strength and resistance to migration into adjacent substrates must meet strict compliance standards. This makes it ideal for premium branding and packaging solutions.

It also performs in rubber compounding and elastomer applications where pigment stability under mechanical stress and heat exposure is a procurement priority. The pigment ensures that the final rubber products retain their aesthetic appeal and structural properties.

The product is supplied as a dry powder, typically in press cake or finished pigment form depending on the downstream application. Standard commercial grades are available as crude pigment or surface-treated variants optimized for specific dispersion systems.

These variants are suitable for solventborne, waterborne, or plastics applications. Technical-grade specifications are the norm, with particle size distribution and tinting strength documented per batch for quality assurance purposes.
