Description

Tricopper Chromate Tetrahydroxide is an inorganic compound with the CAS number 12433-14-6, primarily recognized for its role as a corrosion-inhibiting pigment. This material matters for its ability to provide long-term protection to metal substrates, particularly in harsh environments, by forming a stable, passivating layer. It is needed by manufacturers of anti-corrosive primers, industrial paints, and coatings for the marine, automotive, and construction industries.

Application

• Corrosion-Inhibiting Pigments: A key active component in primers and protective coatings for steel, aluminum, and other metal alloys.
• Marine & Offshore Coatings: Used in paints for ships, oil rigs, and port infrastructure to prevent saltwater corrosion.
• Automotive Primers: Incorporated into primer formulations for vehicle underbodies and chassis components.
• Industrial Maintenance Paints: Essential for coatings applied to bridges, pipelines, storage tanks, and chemical processing plants.
• Aerospace Coatings: Employed in specialized coatings for aircraft components exposed to atmospheric and operational stresses.
• Wood Preservatives: Acts as a fungicidal and anti-corrosive agent in treatments for outdoor wooden structures.
