Description

Disperse Yellow 199 is a high-performance synthetic organic dye belonging to the disperse dye class, identified by CAS NO 71872-58-7. It is engineered to deliver excellent color fastness, brightness, and dispersion stability, which are critical for consistent batch-to-batch results in demanding industrial applications. This product is essential for manufacturers in the textile and polymer industries seeking reliable and vibrant yellow coloration for synthetic fibers.

Application

• Primary dyeing and printing of polyester (PET) fibers and fabrics.
• Coloration of polyamide (nylon) textiles.
• Mass pigmentation and spin-dyeing of synthetic polymers including acetate and acrylic fibers.
• Used in the manufacture of colored plastic masterbatches for films, packaging, and engineering plastics.
• Application in transfer printing processes for textiles.
• Suitable for high-temperature dyeing processes due to its thermal stability.

Quality Control

Our Disperse Yellow 199 is manufactured under a stringent quality management system to ensure it meets the high standards required for industrial dyeing. Each batch is tested for critical parameters including color strength, shade, dispersion stability, and impurity profile. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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.
