Description

Pigment Yellow 65 is a high-performance, diarylide-based organic pigment renowned for its clean, greenish-yellow hue and excellent color strength. This pigment matters for its superior durability, offering good lightfastness, heat stability, and resistance to solvents, making it a cost-effective and reliable coloring agent. It is primarily needed by manufacturers in the plastics, printing inks, coatings, and synthetic fiber industries seeking vibrant and stable yellow coloration for their products.

Application

  • Plastics Coloring: Widely used for coloring PVC, polyolefins (PP, PE), and other polymers, providing excellent dispersion and heat stability during processing.
  • Printing Inks: A key component in solvent-based, water-based, and offset printing inks, delivering strong, opaque yellow shades for packaging and publications.
  • Industrial Coatings: Imparts durable and weather-resistant yellow colors in architectural paints, automotive refinishes, and industrial maintenance coatings.
  • Synthetic Fibers: Employed in the mass coloration of fibers such as polypropylene and polyester, ensuring uniform and fast color.
  • Masterbatch Production: Serves as a primary pigment in the manufacture of color concentrates and compounds for the plastics industry.
  • Rubber Products: Used to color various rubber goods, maintaining color integrity under flexing and environmental exposure.

Quality Control

Our Pigment Yellow 65 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot undergoes comprehensive testing for key parameters including color strength, hue, particle size distribution, and rheological properties. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain optimal color properties.
