Description

C.I. Solvent Orange 11 is a high-purity, synthetic organic pigment belonging to the solvent dye class. This compound is valued for its strong, vibrant orange hue and excellent solubility in non-polar organic media, making it a critical component for imparting color in specialized industrial applications. It is primarily sought after by manufacturers in the plastics, coatings, and specialty ink sectors who require consistent, high-performance colorants for their formulations.

Application

• Coloration of engineering plastics (e.g., ABS, polystyrene, polycarbonate) and synthetic fibers.
• Manufacturing of specialty inks, including for printing on plastics and metals.
• Staining and tinting of waxes, lubricants, and hydrocarbon-based fuels for identification.
• Production of colored lacquers and solvent-based wood stains.
• As a colorant for specialty coatings and varnishes.
• Used in the coloration of certain types of adhesives and sealants.
