Description

Pigment Yellow 16 is a high-performance, diarylide-based organic pigment renowned for its strong, greenish-yellow hue and excellent color strength. This pigment is engineered to deliver superior durability, including good lightfastness and solvent resistance, making it a critical component for achieving consistent, long-lasting coloration. It is primarily utilized by manufacturers in the plastics, printing inks, and coatings industries who require a reliable and cost-effective yellow pigment for demanding applications.

Application

• Plastics Coloring: Widely used for mass coloration of polyolefins (PP, PE), PVC, and other polymers, offering good dispersion and heat stability.
• Printing Inks: A key component in solvent-based, water-based, and offset printing inks, providing bright yellow shades for packaging and publications.
• Industrial Coatings: Formulated into architectural paints, automotive refinishes, and industrial coatings where color consistency and weatherability are essential.
• Masterbatch Production: Used as a concentrated colorant in carrier resins to create standardized color masterbatches for the plastics industry.
• Textile Printing: Employed in specific pigment printing pastes for textiles, contributing to vibrant prints.
• Specialty Applications: Suitable for coloring a variety of materials including rubber, leather finishes, and stationery products.

Quality Control

Our Pigment Yellow 16 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as color strength, hue, particle size distribution, and chemical purity are rigorously tested against established internal specifications. A Certificate of Analysis (COA) detailing these results 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. As a light-sensitive material, prolonged exposure to direct light should be avoided to maintain optimal color properties.
