Pigment red 4

Pigment Red 4 (CAS 2814-77-9 ), also known as D&C Red No. 36, is an azo-based organic pigment delivering a bright, clean red shade across a range of industrial coloring applications.

It is used to impart color in plastics, surface coatings, printing inks, and textile substrates where consistent hue and process compatibility are the primary sourcing criteria for manufacturers.

In plastics and polymer processing, it is incorporated into masterbatches and compound colorants for consumer and packaging goods requiring vivid red tones and reliable dispersion during production.

Coatings formulators use it in solvent-based and industrial paints where strong tinting strength and surface uniformity are required to meet specific aesthetic and performance standards in the field.

In printing and packaging, it is selected for gravure and flexographic ink systems targeting high-impact red reproduction on paper and film substrates for various commercial branding needs.

Textile and leather processors apply it in dyeing and finishing operations where surface coloration of synthetic and natural materials is needed to achieve specific seasonal or industrial colors.

The product is supplied as a dry powder, the standard commercial form for dispersion into resin, solvent, or aqueous systems. Technical grade is the primary market offering available.

Product specifications are typically defined by color strength, purity, and particle size distribution. Packaging is available in fiber drums or bags suited to bulk industrial procurement and logistics.
