Description

Pigment Yellow 16 is a high-performance, diarylide-based organic pigment known for its clean, greenish-yellow hue and excellent color strength. This pigment is valued for its strong tinting power, good lightfastness, and cost-effectiveness in mass coloration. It is primarily used by manufacturers in the plastics, printing inks, and coatings industries to produce vibrant and durable yellow shades in a wide range of products.

Application

Pigment Yellow 16 is a versatile colorant suitable for numerous industrial applications requiring a stable and intense yellow color.

• Plastics Coloring: For mass pigmentation of polyolefins (PP, PE), PVC, polystyrene, and engineering plastics, offering good heat stability and dispersion.
• Printing Inks: Widely used in solvent-based, water-based, and offset printing inks for packaging, publications, and commercial printing.
• Industrial Coatings: Formulated into air-dry and baking enamels, including automotive refinishes, industrial finishes, and decorative paints.
• Masterbatch Production: A key component in the manufacture of color and additive concentrates for the plastics industry.
• Textile Printing: Employed in pigment printing pastes for fabrics.
• Specialty Applications: Used in the coloration of rubber, leather finishes, and stationery products.

Quality Control

Our production of Pigment Yellow 16 adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through comprehensive testing of key parameters including color strength, hue, particle size distribution, and rheological properties. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to support your quality assurance processes.

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.
