Description

Solvent Yellow 13 is a high-performance, oil-soluble azo dye widely recognized for its strong tinctorial strength and excellent solubility in non-polar media. This compound is essential for providing a clean, vibrant yellow hue to a diverse range of industrial materials. It is primarily utilized by manufacturers in the plastics, printing ink, and coatings industries seeking consistent and reliable coloration.

Application

• Plastics Coloring: A primary colorant for polystyrene (PS), polycarbonate (PC), and other engineering plastics requiring high-temperature processing stability.
• Printing Inks: Used in solvent-based and oil-based printing inks for packaging, publications, and specialty printing to achieve bright yellow shades.
• Industrial Coatings: Imparts durable yellow coloration to industrial paints, lacquers, and wood stains.
• Waxes & Greases: Employed for the coloration of petroleum-based products like lubricating greases and candles.
• Office Supplies: A key pigment in the manufacture of colored pencils, crayons, and artist's oil pastels.
• Textile Transfer Printing: Used in specific dye-sublimation processes for synthetic fabrics.
