Trisodium phosphate (15475-67-9) is a versatile chemical compound widely used in metal treatment applications, valued for its basicity, complexation properties, and surface activity.

Rust removal and passivation mechanism: Trisodium phosphate reacts with metal oxides (such as Fe₂O₃) to form iron phosphate complexes, effectively dissolving rust layers. At elevated temperatures or concentrations, it forms insoluble phosphate films (like iron phosphate) on metal surfaces, providing temporary rust prevention.

Trisodium phosphate serves as a cost-effective, multifunctional solution for metal treatment. Our high-quality TSP products come with expert technical support to help industrial operations enhance cleanliness, extend equipment lifespan, and optimize maintenance costs.
