Description

C.I. Azoic Black 20 is a high-performance, insoluble azo pigment renowned for its deep, intense black shade and excellent fastness properties. This pigment is crucial for achieving durable, high-quality coloration in demanding industrial applications where resistance to light, heat, and solvents is paramount. It is primarily needed by manufacturers in the textile, plastics, and coatings industries seeking reliable and cost-effective black pigments.

Application

• Primary application in the textile printing and dyeing of cellulosic fibers like cotton and viscose, where it forms a deep, fast black.
• Coloration of plastics and synthetic resins, including PVC, polyolefins, and rubber, providing good dispersion and heat stability.
• Manufacture of industrial paints and coatings, especially where high opacity and weather resistance are required.
• Production of printing inks for packaging and publications, valued for its color strength and printability.
• Pigmentation of paper and specialty papers requiring a stable black hue.
• Used in the coloring of leather and synthetic leather materials.
