Pigment Red 170 F5RK is a commercial grade of Pigment Red 170 (C.I. 12475), an organic pigment belonging to the naphthol AS azo pigment class. It generally produces a bluish-red to deep red shade and is widely used in industrial coloration systems such as coatings, printing inks, and plastics.
The designation F5RK refers to a specific pigment grade designed to provide balanced dispersion and color performance in different industrial formulations. Like other grades of Pigment Red 170, 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 F5RK is commonly used in applications where consistent red coloration and reliable processing performance are required.

The performance of Pigment Red 170 F5RK is influenced by its naphthol AS pigment chemistry and physical characteristics.
Key properties include:
Color shade
Bluish-red to deep red tone with moderate chroma.
Tinting strength
Moderate to strong tinting strength depending on formulation.
Dispersion characteristics
Designed to disperse effectively in coatings, inks, and plastics using conventional dispersion techniques.
Heat resistance
Suitable for polymer processing at moderate temperatures.
Solvent resistance
Compatible with common solvents used in coatings and printing ink systems.
Exceptional Tinting Strength: Red170 F5RK boasts very high coloring power, allowing for vivid color effects with a small amount of pigment.
Excellent Light Fastness: This pigment resists fading even after prolonged exposure to light, making it ideal for applications requiring high light stability.
Good Weather Fastness: It maintains color stability and durability even in harsh outdoor environments.
Superior Solvent Resistance: It demonstrates good resistance to various solvents, preventing dissolution or migration.
Broad Application Range: Due to its comprehensive performance, it’s widely used in plastics, inks, coatings, textile printing, and other fields.
Vibrant Shade: It provides a bright and pure red hue, enhancing the visual appeal of products.
Pigment Red 170 F5RK 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 certain high-performance pigment classes such as quinacridone or DPP pigments
When selecting Pigment Red 170 F5RK for industrial formulations, several technical factors are typically evaluated:
Processing temperature of plastics or coatings
Lightfastness requirements for indoor or outdoor use
Compatibility with binder or resin systems
Dispersion performance within the formulation
Different grades of Pigment Red 170 may offer variations in particle size distribution and surface treatment depending on the intended application.
