Description

Acid Red 60 is a synthetic, water-soluble azo dye belonging to the acid dye class, known for its bright red color and good lightfastness. It is a critical component for imparting vibrant and durable red shades to various substrates, offering excellent value for industrial coloring applications. This dye is primarily needed by manufacturers in the textile, leather, and paper industries, as well as for coloring inks and certain specialty coatings where a strong red hue is required.

Application

• Textile Dyeing: Primary application for dyeing protein fibers like wool, silk, and nylon to achieve bright red shades.
• Leather Finishing: Used for coloring leather goods, providing rich and uniform coloration.
• Paper Coloring: Employed in the production of colored papers, tissues, and packaging materials.
• Ink Formulation: A key pigment for manufacturing inks used in writing instruments, stamp pads, and flexographic printing.
• Wood Staining: Applied to impart a red tint to wood surfaces in decorative applications.
• Specialty Coatings: Used in formulations for certain industrial and artistic coatings requiring a red colorant.
