Description

Solvent Yellow 15 is a synthetic organic pigment belonging to the diarylide yellow class, widely recognized for its strong, clean yellow hue. This high-performance colorant is valued for its excellent tinctorial strength, good lightfastness, and broad compatibility with non-polar systems. It is an essential material for industrial manufacturers requiring durable and vibrant coloration in plastics, inks, and coatings. The compound is commercially available under the CAS registry number 15876-56-9.

Application

Solvent Yellow 15 is a versatile pigment utilized across multiple industries for its stable color properties. Key application areas include:

• Plastics Coloring: Masterbatch and compound production for polyethylene (PE), polypropylene (PP), polystyrene (PS), and ABS.
• Printing Inks: Formulation of high-quality flexographic, gravure, and offset inks for packaging and publications.
• Industrial Coatings: Pigmentation for air-dry and baked enamels, including automotive refinish and industrial maintenance paints.
• Synthetic Fibers: Mass coloration (dope dyeing) of fibers to achieve excellent wash and light fastness.
• Office Supplies: Coloring for crayons, artist's colors, and other stationery products.
• Rubber Products: Pigmentation for colored rubber goods and latex products.

Quality Control

Our production of Solvent Yellow 15 adheres to stringent quality management protocols 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 comprehensive Certificate of Analysis (COA) detailing these results is 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 ambient temperature (15-25°C). Keep away from strong oxidizing agents and incompatible materials. For long-term storage, ensure the original packaging remains sealed to prevent moisture absorption and contamination.
