What is Pigment Red 48:4

Pigment Red 48:4 (C.I. 15865:4) is an organic azo pigment belonging to the BONA (β-oxynaphthoic acid) pigment family. It is the manganese salt form of Pigment Red 48 and typically provides a bluish-red shade.

The pigment is produced through an azo coupling reaction followed by metal salt formation, which converts the pigment into an insoluble form suitable for industrial coloration. The manganese salt structure contributes to pigment stability and allows it to be used in coatings, printing inks, plastics, and other materials.

Pigment Red 48:4 is part of the Pigment Red 48 series, a group of widely used BONA-type pigments that provide red coloration for many conventional industrial applications.

Advantages

Vivid Shade & High Tinting Strength: Features a bright bluish-red hue with excellent aesthetic appeal. It boasts strong coloring power, requiring only a small amount to achieve the desired shade, offering great cost-effectiveness.
Outstanding Lightfastness & Heat Stability: Reaches a lightfastness level of 7 in air-drying paints and withstands temperatures of 200~290℃ for 5 minutes in PE materials, delivering remarkable stability.
Reliable Core Performance: Non-bleeding, suitable for applications with color fastness requirements such as insulated cables, ensuring consistent and reliable usage effects.
Production-Enhancing Functions: Contains manganese that catalyzes the drying process, improving construction and production efficiency. When toned with chrome molybdate orange, it significantly enhances the hiding power of coatings.
Wide Application Scope: Well-adapted for coloring polyolefins, flexible PVC, coatings, packaging inks and other fields, with strong versatility.

Typical Limitations

Pigment Red 48:4 may have certain limitations depending on the durability requirements of the final application.

Typical limitations include:

Moderate lightfastness, particularly in outdoor environments
Limited heat resistance compared with high-performance pigment types
Possible bleeding or migration in certain plastic formulations
Not typically selected for applications requiring long-term weather resistance

Buyer Guidance

When selecting Pigment Red 48:4 for industrial formulations, several factors are commonly considered:

Processing temperature of plastics or coatings
Lightfastness requirements for indoor or outdoor applications
Compatibility with binder or resin systems
Dispersion performance within the formulation

For applications requiring higher durability, improved weather resistance, or greater thermal stability, alternative pigment chemistries may be evaluated.
