Description

Disperseblue79 CAS NO 3956-55-6 is a high-performance anthraquinone-based disperse dye. This compound is valued for its excellent color fastness and stability, making it a critical component in synthetic fiber coloration. It is primarily required by manufacturers in the textile and plastics industries for producing vibrant and durable blue shades.

Application

• Primary dyeing and printing of hydrophobic synthetic fibers such as polyester, acetate, and nylon.
• Mass coloration of plastics and synthetic resins to achieve uniform blue pigmentation.
• Manufacturing of inks and toners for specialized printing applications.
• Coloration of automotive textiles and interior fabrics requiring high light and wash fastness.
• Production of colored masterbatches for the plastics compounding industry.
• Used in research and development for creating new polymeric colorant formulations.

Quality Control

Our Disperseblue79 is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise color strength, purity, and application performance specifications. A comprehensive Certificate of Analysis (COA) detailing parameters such as purity, shade, and particle size distribution is provided with each shipment to guarantee consistency and reliability for your production processes.

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). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
