Product performance: Strontium phosphate combines with the metal surface to form a stable chelate, which has excellent adhesion and anti-corrosion properties on metal substrates, especially aluminum alloys, aluminum-magnesium alloys and galvanized sheet surfaces. Low toxicity and rust-proof. It is widely used in the production of water-based coatings, inorganic coatings, organic coatings, and water-based steel structures. It can effectively increase the medium resistance of the coating.
The main function is to prevent metal corrosion and improve the protective effect of the paint film on the metal surface.
Relying on chemical reactions to change the properties of the surface or the characteristics of the reaction products to achieve the purpose of rust prevention, it has a good effect on enhancing the salt spray resistance of light metal coatings. 

Main applications: It can be used for water-based steel structure coatings, water-based epoxy primers, perchlorethylene primers, epoxy resin primers, polyurethane primers, etc. It is the most suitable anti-rust pigment for maintenance primers, shop primers and anti-corrosion primers. It is also one of the excellent rust-passivating pigments in the water-based base-in-one system. Solve water-based steel structure rust resistance, salt spray resistance, and environmental protection issues, etc.
