Description

Chromate(5-), Bis[4-Hydroxy-6-[(2-Hydroxy- 5-Methylphenyl)Azo]-3-[(2-Hydroxy-5-Nitro-3-Sulfophenyl )Azo]-2-Naphthalenesulfonato(4-)]-, Potassium Sodium is a complex, high-purity azo dye-based chromate salt. This compound matters for its ability to provide exceptional color fastness and stability in demanding industrial environments. It is primarily needed by manufacturers in the textile, leather, and specialty coatings industries seeking advanced, high-performance colorants.

Application

• Textile Dyeing: Used for dyeing natural and synthetic fibers, particularly where high light and wash fastness are required.
• Leather Finishing: Imparts deep, vibrant colors to leather goods with excellent rub resistance.
• Specialty Inks: A key component in the formulation of high-quality printing inks for packaging and security applications.
• Industrial Coatings: Provides coloration for coatings used in automotive, aerospace, and architectural applications.
• Paper Coloring: Employed in the production of high-grade colored papers and decorative laminates.
• Plastic Masterbatch: Used as a colorant in the production of masterbatches for coloring plastics.
• Research & Development: Serves as a reference standard and intermediate in the synthesis of novel dye molecules.
