Product Description

Product Description

Pigment Red 170 (Permanent Red F5RK),A Versatile Red Pigment for Leather, Rubber, Fine Arts, and Cosmetics

Pigment Red 170 (CAS 2786-76-7), commercially known as Permanent Red F5RK, is a β-naphthol type monoazo pigment recognized for its strong, bluish-red shade. The F5RK designation refers specifically to the β-crystal form, which is characterized by its semi-transparent nature. This crystal structure provides excellent transparency and color richness, making it particularly suitable for applications where color depth and clarity are valued over high hiding power. Its robust fastness properties and non-toxic profile support its use in a diverse range of specialized industrial and consumer applications.

Key Features & Advantages
Excellent Transparency & Color Richness:	The β-crystal form (F5RK) offers a semi-transparent color laydown. This property is crucial for achieving deep, clear tones in wood stains, artistic glazes, and leather finishes, allowing the substrate's texture to show through while imparting vibrant color.
Strong Overall Fastness:	Exhibits very good to excellent resistance to light (grade 6-7 for the β-type), water, oils, acids, and alkalis (all grade 5), ensuring color stability in various environments.
Good Dispersibility:	The fine, rod-shaped particles (average 0.18-0.22 μm) contribute to good dispersibility in various liquid and paste systems, which is essential for uniform coloration in wood stains, leather coatings, and cosmetic formulations.
Non-Migrating and Solvent Stable:	Shows excellent resistance to migration and good stability in common solvents, preventing issues like bleeding in rubber or leather, and ensuring clean application.
Broad Compatibility:	Suitable for formulation in solvent-based, water-based, and paste systems, facilitating its use across different industries from industrial rubber coloring to fine art paints and cosmetic products.
