Zinc Phosphate
Zinc phosphate is a classic, heavy-metal-free anti-corrosion pigment widely used as a primary corrosion inhibitor in solvent-based and water-based protective coatings. It functions through a combination of phosphate passivation and zinc ion release, forming a dense protective layer on metal surfaces. Zinc phosphate is an established replacement for lead-based primers, compliant with REACH and RoHS regulations.
