Description

Pigment Yellow 170 is a high-performance, monoazo-based organic pigment renowned for its excellent color strength and durability. This pigment is a critical component for achieving bright, clean, and highly opaque yellow shades in demanding applications. It is primarily sought after by manufacturers in the plastics, coatings, and printing ink industries who require superior lightfastness, weather resistance, and thermal stability. Our supply ensures consistent quality and reliable performance for your most challenging formulations.

Application

• Plastics Coloring: For coloring a wide range of polymers including PVC, polyolefins (PP, PE), and engineering plastics, offering excellent dispersion and heat stability during processing.
• Industrial Coatings: Used in automotive OEM and refinish paints, coil coatings, and industrial finishes where durability and color retention are paramount.
• Printing Inks: A key pigment for offset, gravure, and flexographic inks, providing strong, transparent yellow tones for packaging and publications.
• Masterbatch Production: Ideal for creating concentrated color masterbatches for efficient and uniform coloring of plastics.
• Architectural Paints: Suitable for exterior and interior decorative paints requiring good lightfastness and weatherability.
• Specialty Applications: Can be used in colored pencils, artists' colors, and other specialty applications requiring a pure yellow hue.
