Description

Bis[2-[[4-[Ethyl(2-Hydroxyethyl)Amino]Phenyl]Azo]-6-Methoxy-3-Methylbenzothiazolium] Sulphate is a high-purity cationic diazo dye salt, valued for its intense color and strong affinity for various substrates. This compound is engineered for applications requiring excellent lightfastness and washfastness properties. It is a critical component for manufacturers in the textile, paper, and specialty ink industries seeking reliable and consistent color performance.

Application

• Textile Dyeing: Primary application for dyeing acrylic, modacrylic, and other cationic-dyeable synthetic fibers, providing vibrant and durable shades.
• Paper Coloring: Used in the production of specialty papers, including colored tissue, packaging, and decorative papers, where strong, bleed-resistant color is required.
• Ink Formulation: A key pigment for manufacturing inks used in flexographic, gravure, and inkjet printing, particularly on non-porous surfaces.
• Leather Finishing: Employed in dyeing leather and synthetic leather materials to achieve uniform and rich coloration.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis of tissue samples.
• Plastics and Polymers: For mass coloration of certain plastics where high thermal stability and color consistency are needed.
