What is Pigment Red 63:1

Pigment Red 63:1 (C.I. 15880:1) is an organic azo pigment belonging to the BONA (β-oxynaphthoic acid) pigment family. It is the calcium salt form of Pigment Red 63 and typically provides a bluish-red to deep red shade.

The pigment is synthesized through an azo coupling reaction followed by conversion into a metal salt form. This transformation produces an insoluble organic pigment that is suitable for use in a variety of industrial coloration systems. The calcium salt structure helps improve pigment stability and reduces solubility compared with the free acid form.

Pigment Red 63:1 has historically been used in coatings, printing inks, plastics, and other industrial applications where a conventional red pigment is required.

Advantages

Unique and Bright Hue: As a calcium lake (also known as Lithol Rubine 2R), it exhibits a dark bluish-red jujube color with striking and clean appearance, strong visual appeal, and can endow various products with distinct recognition.
High Tinting Strength: It has strong coloring performance, and only a small amount of addition is needed to achieve full and rich color effects, effectively reducing the production material cost.
Cost-Effective Advantage: It features excellent balance between performance and cost, with economic benefits while ensuring stable coloring effect, making it a high-value choice for various industries.
Excellent Solvent Resistance: Only slight bleeding occurs in common solvents such as alcohols, ketones and aromatics, with outstanding color stability, suitable for multiple application scenarios.
Wide Application Adaptability: Applicable to coloring of low-cost coatings, artificial leather, plastics (especially polyolefin products) and rubber. It can also exert stable coloring performance in offset, gravure and flexographic inks.

Typical Limitations

Pigment Red 63:1 may present certain limitations depending on the durability requirements of the application.

Typical limitations include:

Moderate lightfastness, particularly under prolonged outdoor exposure
Limited heat resistance compared with high-performance pigments
Possible bleeding or migration in certain plastic formulations
Not typically used where long-term weather resistance is required

Buyer Guidance

When selecting Pigment Red 63:1 for industrial formulations, several technical aspects are commonly considered:

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

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