Description

Tetrasodium [Mu-[[3,3'-[(3,3'-Dihydroxy[1,1'-Biphenyl]-4,4'-Diyl)Bis(Azo)]Bis[5-Ethoxy-4-Hydroxynaphthalene-2,7-Disulphonato]](8-)]]Dicuprate(4-) is a high-performance, water-soluble copper phthalocyanine-based pigment and complex. This compound is valued for its exceptional color strength, stability, and vibrant blue to greenish-blue hue, making it a critical component in demanding industrial applications. It is primarily sought after by manufacturers in the coatings, inks, plastics, and specialty textile industries where superior colorfastness and chemical resistance are non-negotiable.

Application

• Industrial Coatings and Paints: Used in automotive, marine, and architectural coatings for its excellent weatherability, lightfastness, and chemical resistance.
• Printing Inks: A key pigment for high-quality offset, gravure, and flexographic inks, providing brilliant color and stability on various substrates.
• Plastics and Masterbatch Coloration: Imparts stable and intense coloration to polymers like PVC, polyolefins, and engineering plastics during processing.
• Textile Dyeing and Printing: Employed in the coloration of synthetic fibers and specialty fabrics requiring high wash and light fastness.
• Paper Coloration: Used in the production of high-grade colored papers and decorative laminates.
• Artist Colors and Specialty Pigments: A component in professional-grade artists' paints and other high-performance colorant systems.

Quality Control

Our production of this pigment adheres to stringent quality control protocols to ensure batch-to-batch consistency in color value, strength, and purity. Quality is verified through advanced analytical techniques including spectrophotometry and chromatography. A comprehensive Certificate of Analysis (COA) detailing purity, shade, physical properties, and performance characteristics is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect performance.
