Description

Basic Red 18:1 is a synthetic cationic dye belonging to the azo class, widely recognized for its vibrant red color and strong affinity for polyacrylonitrile fibers. Its primary value lies in providing excellent color fastness, brightness, and leveling properties in demanding industrial dyeing processes. This product is essential for manufacturers in the textile, paper, and leather industries seeking reliable and consistent coloration for synthetic materials.

Application

• Textile Dyeing: Primary application for dyeing acrylic, modacrylic, and other cationic-dyeable synthetic fibers, offering excellent exhaustion and build-up.
• Paper Coloring: Used in the production of specialty papers, including colored tissue, packaging, and decorative papers, where a bright red hue is required.
• Leather Finishing: Employed in the dyeing of leather goods to achieve uniform and deep red shades with good rub fastness.
• Ink Manufacturing: Serves as a colorant for certain types of inks, particularly where compatibility with specific substrates is needed.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis, depending on purity grade.
