Pigment red 273

Pigment Red 273 (CAS 68583-95-9), also sold as Red 40 Lake and Food Red 17:1, is a high-performance azo lake pigment derived from the aluminum precipitation of Allura Red AC.

It delivers bright, stable red coloration across a range of industrial substrates where soluble dyes are unsuitable. In plastics and polymer compounding, it provides consistent red hues in rigid and flexible formulations.

Bleed resistance is a critical specification for this material. Printing ink manufacturers use it in packaging inks where sharp color strength and substrate adhesion are required across both solvent-based and aqueous systems.

Textile and leather finishers apply it in surface coatings and pigment printing pastes to achieve uniform red tones on non-dyeable synthetic substrates. It is highly valued for its versatility in these sectors.

In construction materials, it colors cement-based products, coatings, and architectural finishes. Weather resistance and alkali stability determine pigment selection for these demanding outdoor and structural applications.

Pigment Red 273 is supplied as a dry powder, typically in press cake form for ink and coating applications. Standard grades are differentiated by oil absorption, particle size distribution, and tinting strength.

These specifications ensure the product matches specific end-use requirements. Technical-grade material is the primary commercial offering, with specialty grades available for high-performance printing and plastics applications.
