Description

C.I. Basic Red 12, Tannate is a cationic dye complex formed with tannic acid, valued for its strong affinity to substrates with anionic character. This compound is essential for creating vibrant, durable red colorations in specialized industrial applications where standard dyes may not adhere effectively. It is primarily needed by manufacturers in the textile, paper, leather, and specialty ink industries seeking high-performance colorants.

Application

• Textile Dyeing: Used for dyeing acrylic, modacrylic, and other synthetic fibers, as well as for silk and wool.
• Paper Coloring: Imparts color to specialty papers, including decorative and security papers.
• Leather Finishing: Applied in the dyeing of leather goods for a uniform and rich red hue.
• Biological Staining: Employed as a histological stain in microscopy for tissue sample analysis.
• Ink Manufacturing: A colorant component in the production of inks for pens, stamp pads, and other applications.
• Wood Staining: Used to color wood and wood-based products.
