What is Pigment Red 48:3

Pigment Red 48:3 (C.I. 15865:3) is an organic azo pigment belonging to the BONA (β-oxynaphthoic acid) pigment family. It is the strontium salt form of Pigment Red 48 and typically produces a bluish-red shade.

The pigment is manufactured through an azo coupling reaction followed by conversion into a metal salt form. The metal salt structure improves pigment insolubility and contributes to stability in various industrial formulations. As a result, Pigment Red 48:3 is used as an insoluble colorant in coatings, printing inks, plastics, and other materials.

Pigment Red 48:3 is part of a group of widely used azo pigments that provide red coloration for many conventional industrial applications.

Key Performance Properties Related to Applications

The application behavior of Pigment Red 48:3 is influenced by its chemical structure and metal salt composition.

Key properties include:

Color shade
Bluish-red tone with moderate chroma.
Tinting strength
Moderate to relatively strong tinting strength typical of BONA-type pigments.
Dispersion characteristics
Can be dispersed in coatings, inks, and plastics using standard dispersion processes.
Heat resistance
Moderate thermal stability suitable for certain plastic processing temperatures.
Solvent resistance
Generally compatible with common solvents used in coatings and printing inks.

Advantages

Vivid, Long-lasting Color with Excellent Tinting Strength: Displays a bright and rich bluish-red shade, featuring full and non-fading color. High color concentration and good uniformity ensure ideal coloring effects with minimal addition.
Superior Lightfastness: Achieves a lightfastness rating of 6 at 0.2% concentration in transparent formulations. Maintains color stability even in strong light conditions, keeping products bright and vivid after long-term exposure.
Outstanding Weather Resistance and Chemical Resistance: Heat-resistant (up to 180℃) and humidity-resistant, suitable for harsh environments such as outdoor use. Also possesses excellent resistance to water, oil, acid and alkali, effectively preventing color change and enhancing product durability.
Excellent Migration Resistance: Performs exceptionally well in flexible PVC and other materials, avoiding color migration to ensure the purity and stability of product coloring.
High Compatibility and Wide Application: Compatible with various plastic substrates (e.g., PVC, LDPE, PS, etc.) and ink systems (offset, solvent-based, water-based, etc.). With excellent dispersibility, it meets the coloring needs of different industrial scenarios.

Typical Limitations

Pigment Red 48:3 may have 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 used where long-term weather resistance is required

Buyer Guidance

When selecting Pigment Red 48:3 for industrial applications, several formulation factors are usually considered:

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

Applications requiring higher durability, improved weather resistance, or greater heat stability may evaluate alternative pigment chemistries.
