Description

1-[[2,5-Dimethyl-4-(Phenylazo)Phenyl]Azo]-2-Naphthol is a high-performance synthetic organic pigment belonging to the azo dye class. This compound is valued for its ability to provide intense, stable coloration in a variety of demanding industrial applications. It is primarily sought after by manufacturers in the plastics, inks, and coatings industries who require reliable and consistent pigmentation.

Application

• Plastics Coloring: Used as a masterbatch pigment for coloring polyolefins (PP, PE), PVC, and engineering plastics, offering good heat stability and dispersion.
• Industrial Coatings: Imparts durable color to industrial paints, automotive refinishes, and powder coatings where lightfastness is required.
• Printing Inks: Employed in the formulation of solvent-based and packaging inks for flexographic and gravure printing.
• Synthetic Fibers: Acts as a colorant in the mass pigmentation of synthetic fibers such as polyamide and polyester.
• Specialty Products: Suitable for coloring a range of specialty products including sealants, adhesives, and certain rubber compounds.

Quality Control

Every batch of our azo pigments is produced under strict quality management systems. We ensure compliance with relevant industry standards for colorants, with key parameters including color strength, hue, and physical properties rigorously tested. A Certificate of Analysis (COA) detailing purity, ash content, and specific performance tests is provided with each shipment to guarantee batch-to-batch consistency.

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 incompatible materials and sources of ignition. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
