Description

Disperse Yellow 2 is a synthetic organic colorant belonging to the azo dye class, widely recognized for its bright yellow hue. This product is valued for its excellent dispersion properties and color fastness, making it a critical component in synthetic fiber coloration. It is primarily utilized by manufacturers in the textile and plastics industries seeking consistent, high-performance pigments for their production processes.

Application

• Textile Dyeing: Primary application for dyeing hydrophobic synthetic fibers such as polyester, acetate, and nylon, offering good wash and light fastness.
• Plastics Coloring: Used as a colorant for thermoplastics including polystyrene, polycarbonate, and acrylic resins to achieve uniform yellow shades.
• Ink Formulation: Employed in the production of specialty inks for printing on synthetic fabrics and other polymeric substrates.
• Masterbatch Production: A key ingredient in color concentrate masterbatches used for bulk coloring of plastic materials during molding or extrusion.
• Research & Development: Serves as a reference standard or starting material in chemical R&D for developing new dyes and studying dyeing mechanisms.

Quality Control

Our Disperse Yellow 2 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against established specifications for critical parameters including color strength, dispersion stability, and impurity profile. A Certificate of Analysis (COA) detailing these results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
