Description
Pigment Yellow 55 is a high-performance, monoazo-based organic pigment known for its clean, greenish-yellow hue and excellent color strength. This pigment is valued for its good lightfastness and heat stability, making it a reliable choice for demanding coloration applications. It is primarily used by manufacturers in the plastics, coatings, and printing ink industries seeking consistent and durable yellow shades.
Application
- Plastics Coloring: For coloring a wide range of polymers, including PVC, polyolefins, and engineering plastics, offering good dispersion and heat resistance.
- Industrial Coatings: Imparts durable yellow coloration to industrial paints, automotive refinishes, and coil coatings.
- Printing Inks: Used in the formulation of various printing inks, including packaging and publication gravure inks, for its color intensity.
- Masterbatch Production: An essential colorant for creating concentrated pigment preparations used in plastic processing.
- Synthetic Fibers: Employed in the mass coloration of synthetic fibers like polyamide and polyester.
- Leather Finishes: Provides coloration for finishes and coatings applied to leather goods.
