🧪 Product Description

Magnesium Zinc Phosphate is a high-performance inorganic anticorrosive phosphate that combines the protective properties of magnesium ions and zinc ions. It is widely used in industrial coatings, metal surface treatment, and corrosion protection systems.

Compared with conventional zinc phosphate, Magnesium Zinc Phosphate offers enhanced corrosion resistance, lower solubility, and better compatibility with modern eco-friendly formulations, especially water-based coatings.
