Description

Disperse Yellow 211 is a high-performance synthetic organic dye belonging to the disperse dye class, widely recognized for its excellent color fastness and dispersion properties. This product is engineered to deliver vibrant, consistent yellow coloration with superior thermal stability, making it a critical component for demanding industrial dyeing processes. It is primarily used by manufacturers in the textile and plastics industries seeking reliable and efficient coloring agents for synthetic fibers.

Application

• Primary dyeing of polyester (PET) fibers and fabrics for apparel and home textiles.
• Coloration of polyamide (nylon) fibers, including those used in automotive interiors and sportswear.
• Mass pigmentation and spin dyeing of synthetic polymers such as polyester and acetate.
• Printing applications on synthetic textiles, requiring excellent wash and sublimation fastness.
• Dyeing of plastic materials including certain engineering plastics where color consistency is paramount.
• Used in combination with other disperse dyes to achieve a wide range of custom yellow to orange shades.

Quality Control

Our Disperse Yellow 211 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Every lot is tested against comprehensive specifications for color strength, dispersion stability, and impurity profiles. Certificates of Analysis (COA) documenting purity, shade, and physical properties are available upon request 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance.
