Description
1. Product Overview
Anti-Corrosion Pigment Zinc Phosphate 95% is a high-performance inorganic corrosion-inhibiting pigment widely used in protective coatings and industrial paint formulations. It functions as an effective anti-corrosive agent that provides long-term protection for metal substrates by forming a stable passivation layer that inhibits oxidation and electrochemical corrosion.
As a modern alternative to traditional lead- and chromate-based pigments, Zinc Phosphate offers strong corrosion resistance while meeting increasingly stringent environmental and regulatory requirements. Strategically, it is a critical raw material in industrial coating systems designed to extend asset life, reduce maintenance costs, and enhance durability across infrastructure, marine, automotive, and heavy industry sectors.
