Description

Pigment Red 184 is a high-performance, synthetic organic pigment belonging to the benzimidazolone class, valued for its excellent color strength and durability. This pigment is engineered to provide superior lightfastness, weather resistance, and thermal stability, making it a critical component for demanding applications. It is primarily sought after by manufacturers in the coatings, plastics, and printing ink industries who require a reliable and vivid red hue for their products.

Application

• Industrial Coatings: Used in automotive OEM and refinish paints, industrial machinery coatings, and coil coatings for its excellent exterior durability and color retention.
• Plastics Coloring: Ideal for coloring engineering plastics, PVC, polyolefins, and synthetic fibers, offering good dispersion and heat stability during processing.
• Printing Inks: Employed in high-quality packaging inks, publication gravure inks, and decorative laminates requiring strong, fade-resistant color.
• Masterbatch Production: A key component for creating color concentrates and masterbatches used in plastic and fiber manufacturing.
• Specialty Applications: Suitable for artists' colors, leather finishes, and other applications demanding a pure, stable red pigment.
