Description
Pigment Red 149 (CAS 4948-15-6) is a high-performance perylene-based organic pigment, commercially known as Pv Fast Red B, Perylene Red BL, and C.I. Pigment Red 149 under colour index reference CI 71137. It carries no E-code designation and is identified under EC number 225-590-9 with molecular formula C40H26N2O4.
In plastics and polymer compounding, PR-149 delivers strong red coloration with notable heat and light stability, making it suitable for engineering resins processed at elevated temperatures. In industrial coatings and printing inks, its surface-active behaviour supports pigment wetting and dispersion, improving film uniformity and reducing flocculation in solvent-borne and water-borne systems.
PR-149 is supplied as a dry powder and is subject to REACH registration requirements for EU-based procurement. Buyers should confirm supplier REACH compliance documentation and Safety Data Sheet availability. Standard packaging formats typically include fibre drums or multi-wall bags depending on order volume.
