Pigment red 254

Pigment Red 254 (CAS 84632-65-5), commonly abbreviated as PR254 and belonging to the diketopyrrolopyrrole (DPP) pigment class, delivers a high-chroma, bluish-red hue with exceptional lightfastness and heat stability. It is a benchmark colorant for demanding applications where color strength and durability under processing stress are non-negotiable sourcing criteria for industrial manufacturers and chemical distributors.

In automotive OEM and refinish coatings, PR254 is a preferred red pigment for basecoat formulations requiring long-term weatherfastness and resistance to UV degradation across various environmental conditions. Plastics processors use it in engineering polymers such as polypropylene and polyamide, where its thermal stability supports high-temperature extrusion and injection molding without significant color shift.

Printing ink manufacturers incorporate it into high-end packaging inks, particularly offset and gravure systems, where clean masstone and strong tinting strength are critical for brand consistency. Industrial and decorative coatings formulators also select it for exterior architectural finishes demanding fade resistance over extended service life in harsh outdoor climates and high-exposure areas.

PR254 is supplied as a dry powder, with press cake forms available from select manufacturers. Standard commercial grades are differentiated by particle size distribution and surface treatment for specific uses. Technical and high-purity grades are available, with specifications typically aligned to customer color strength and dispersibility requirements rather than specific pharmacopeial standards or certifications.
