Calcium Zinc Phosphate is a white to off-white inorganic phosphate compound widely used as an environmentally friendly anti-corrosion pigment. It is designed to replace traditional heavy-metal-based inhibitors and offers excellent corrosion protection through the formation of a stable phosphate passivation layer on metal substrates.
This product is valued for its low toxicity, thermal stability, and long-term corrosion resistance, making it suitable for industrial coatings, primers, and metal surface treatment formulations.
