Description

Pigment Yellow 111 is a high-performance, monoazo-based organic pigment known for its clean, greenish-yellow hue and excellent durability. This pigment matters for formulators seeking a reliable colorant that offers strong tinting strength, good lightfastness, and heat stability for demanding industrial applications. It is primarily needed by manufacturers in the plastics, coatings, and printing ink industries, where consistent color quality and performance under processing conditions are critical.

Application

• Plastics Coloring: For coloring a wide range of polymers including PVC, polyolefins (PP, PE), and engineering plastics, offering good dispersion and heat stability.
• Industrial Coatings: Used in solvent-based and coil coatings for automotive, agricultural, and construction equipment, providing excellent weatherability.
• Printing Inks: A key component in packaging and publication gravure and flexographic inks, valued for its color strength and print quality.
• Masterbatch Production: An essential pigment for creating concentrated color masterbatches used in plastic extrusion and molding processes.
• Synthetic Fibers: Employed in the mass coloration of fibers, ensuring uniform and fade-resistant color.
• Specialty Applications: Suitable for coloring artists' colors, stationery, and other specialty products requiring a vivid yellow shade.
