Description

Chromate(3-), [2-hydroxy-3-[[2-hydroxy-8-[(methoxycarbonyl)amino]-1-naphthalenyl]azo]-5-nitrobenzenesulfonato(3-)][2-hydroxy-3-[(2-hydroxy-1-naphthalenyl)azo]-5-nitrobenzenesulfonato(3-)]-, 2-(methylamino)ethanol sodium salts is a complex chromium-based azo dye lake, specifically engineered for high-performance coloration. This compound is valued for its excellent lightfastness, thermal stability, and vibrant hue, making it a critical component in demanding industrial applications. It is primarily sought after by manufacturers in the plastics, specialty coatings, and ink industries where consistent, durable color is paramount.

Application

• Pigmentation for Engineering Plastics: Imparts stable, heat-resistant color to polymers such as polycarbonate, ABS, and nylon used in automotive components and consumer electronics.
• Industrial and Automotive Coatings: Used in formulations requiring high durability, UV resistance, and color consistency for exterior finishes and industrial equipment.
• Specialty Printing Inks: Employed in high-quality packaging, security printing, and other inks where superior lightfastness and chemical resistance are required.
• Coloration of Synthetic Fibers: Suitable for spin-dyeing processes where the pigment is incorporated directly into the polymer melt before extrusion.
• Masterbatch Production: A key ingredient in color concentrates (masterbatches) for uniform dispersion and efficient coloring of bulk plastics.
• Artists' and Professional-Grade Paints: Used in the manufacture of high-performance paints and artist pigments prized for permanence and color intensity.

Quality Control

Our production of Chromate(3-), [2-hydroxy-3-[[2-hydroxy-8-[(methoxycarbonyl)amino]-1-naphthalenyl]azo]-5-nitrobenzenesulfonato(3-)][2-hydroxy-3-[(2-hydroxy-1-naphthalenyl)azo]-5-nitrobenzenesulfonato(3-)]-, 2-(methylamino)ethanol sodium salts adheres to a rigorous quality management system. Each batch is tested to ensure consistent performance in color strength, hue, and physical properties. Certificates of Analysis (COA) documenting key parameters such as purity, heavy metal content, and specific identification 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, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance. Keep away from incompatible materials.
