Description

Pigment Orange 16 is a high-performance, monoazo-based organic pigment renowned for its bright, reddish-orange hue and excellent color strength. This pigment is a critical component for achieving durable and vibrant coloration in a wide range of industrial applications. It is primarily sought after by manufacturers in the plastics, coatings, inks, and synthetic fibers industries who require consistent quality and reliable performance in their finished products.

Application

• Plastics Coloring: Widely used for coloring polyolefins (PP, PE), PVC, and engineering plastics, offering good heat stability and dispersion.
• Industrial Coatings: Imparts a bright orange shade in solvent-based and water-based industrial paints, including automotive refinishes and machinery coatings.
• Printing Inks: A key pigment for flexographic, gravure, and offset inks, providing excellent printability and color consistency for packaging and publications.
• Synthetic Fibers: Used in the mass coloration of fibers such as polyamide and polyester during the spinning process.
• Masterbatch Production: An essential raw material for creating high-concentration color masterbatches used in plastic processing.
• Rubber and Elastomers: Provides coloration for technical rubber goods, footwear, and other elastomeric products.
