Description

Lead Chromate CAS NO 7758-97-6 is an inorganic compound known for its vibrant yellow to orange pigment properties. This material is valued for its excellent opacity, lightfastness, and chemical resistance, making it a critical component in high-performance colorant systems. It is primarily sought after by manufacturers in the coatings, plastics, and specialty printing ink industries for creating durable and vivid colors.

Application

• Pigment for Industrial Coatings: Used in primers, marine paints, and traffic marking paints for its corrosion-inhibiting properties and bright color.
• Plastics and Masterbatch Coloring: Imparts stable yellow and orange hues to PVC, polyolefins, and other polymers.
• Printing Inks: Employed in specialty printing inks where high opacity and chemical stability are required.
• Ceramic Glazes and Enamels: Acts as a colorant in the production of ceramic tiles and sanitaryware.
• Artists' Colors: A traditional pigment (Chrome Yellow) used in oil and acrylic paints.
• Safety and Warning Signage: Provides the high-visibility yellow color for industrial safety applications.
