What is Pigment Red 170 F3RK

Pigment Red 170 F3RK is a commercial grade of Pigment Red 170 (C.I. 12475), an organic pigment belonging to the naphthol AS azo pigment class. It generally provides a bluish-red to deep red shade and is widely used in industrial coloration applications such as coatings, printing inks, and plastics.

The designation F3RK typically refers to a specific pigment grade developed for improved dispersion and color consistency in industrial formulations. Like other Pigment Red 170 grades, it is produced through an azo coupling reaction involving diazonium compounds and naphthol AS coupling components, resulting in an insoluble organic pigment.

Pigment Red 170 F3RK is commonly used in formulations where stable red coloration and balanced performance properties are required.

Advantages

Vibrant & Pure Color Performance: Features a bright, clean neutral red hue (transparent type with blue undertone, opaque type with pure neutral red) and exceptional tinting strength. Boasting a specific surface area of 23 m²/g, it delivers striking visual appeal and vivid color development, enhancing product attractiveness.
Superior Lightfastness: Transparent type offers lightfastness Grade 6, while opaque type reaches Grade 7. Resists fading under prolonged light or intense indoor lighting, ensuring long-lasting color integrity in both full shade and tint applications.
Excellent Weatherability: Maintains stable color and performance in harsh outdoor environments, with strong resistance to UV radiation, moisture, and temperature fluctuations. Ideal for exterior coatings and long-term outdoor applications.
High Hiding Power & Opacity: Delivers excellent covering power, enabling vibrant color development even at low pigment concentrations. The opaque type excels in opacity, ensuring efficient and cost-effective coverage.
Strong Solvent & Chemical Stability: Resists a wide range of solvents (xylene, ethanol, ethyl acetate, etc.) and demonstrates good resistance to 5% HCl, 5% NaOH, soap solutions, and creams. Ensures durable performance in diverse chemical environments and formulations.

Typical Limitations

Pigment Red 170 F3RK may present certain limitations depending on application requirements.

Typical limitations include:

Lightfastness may vary depending on exposure conditions
Heat resistance may be limited for high-temperature engineering plastics
Durability may be lower than some high-performance pigment classes such as quinacridone or perylene pigments

Buyer Guidance

When evaluating Pigment Red 170 F3RK for industrial formulations, several technical aspects are commonly considered:

Processing temperature of plastics or coatings
Required durability and lightfastness
Compatibility with binder or resin systems
Dispersion behavior in the formulation

Different commercial grades of Pigment Red 170 may offer varying particle sizes or surface treatments depending on the intended application.
