Description

Barium Bis[2-[(2-Hydroxy-1-Naphthyl)Azo]Benzoate] is a high-purity metallized azo pigment, valued for its excellent color strength and stability. This compound is essential for applications requiring durable, vivid red to maroon coloration with strong opacity. It is primarily sought by manufacturers in the coatings, plastics, and specialty printing ink industries for high-performance formulations.

Application

• Industrial Coatings: Used in automotive, coil, and industrial maintenance paints for its weather resistance and color fastness.
• Plastics Coloring: Imparts stable red shades to engineering plastics, PVC, and polyolefins during high-temperature processing.
• Printing Inks: A key pigment for high-quality packaging, security, and specialty printing inks requiring lightfastness.
• Masterbatch Production: Serves as a concentrated colorant for creating pigment masterbatches used in polymer compounding.
• Artists' Colors: Employed in the formulation of high-grade artists' paints and pigments.
• Textile Pigments: Used in pigment printing for textiles where wash and light fastness are critical.
