Description

Hc Yellow 13 is a synthetic organic pigment belonging to the diarylide yellow chemical class. This high-performance colorant is valued for its excellent tinting strength, good lightfastness, and strong solvent resistance, making it a critical component for demanding industrial applications. It is primarily utilized by manufacturers in the plastics, coatings, and specialty inks industries seeking durable and vibrant yellow coloration.

Application

• Plastics Coloring: Masterbatch and compound production for polyethylene (PE), polypropylene (PP), polystyrene (PS), and ABS resins.
• Industrial Coatings: Pigmentation for automotive refinish paints, industrial maintenance coatings, and decorative paints requiring weather resistance.
• Printing Inks: Formulation of solvent-based and UV-curable inks for packaging, commercial printing, and specialty applications.
• Synthetic Fibers: Mass coloration (dope dyeing) of polyamide and polyester fibers to achieve colorfast yarns.
• Rubber Products: Coloring of technical rubber goods, footwear, and other elastomeric materials.
• Artists' Colors: High-grade pigment for professional artists' oil and acrylic paints.
