Zinc phosphate is a white non-toxic anti-rust pigment. It is a new generation of non-toxic and pollution-free anti-rust pigment with excellent anti-corrosion effect. It can effectively replace the traditional anti-corrosion pigments containing heavy metals such as lead, chromium, red lead, and zinc chrome yellow. Rust pigments are ideal new varieties of anti-rust pigments in the coating industry.
Features: Zinc phosphate has strong complexing ability in trivalent iron ions. The phosphate ion of zinc phosphate reacts with the iron anode to form a strong protective film with iron phosphate as the main body. This dense purification film is insoluble in water, has high hardness, and has excellent adhesion and exhibits excellent rust resistance. In addition, because the pigment is white, it can be color-matched as needed to match the topcoat without restriction, thereby simplifying the painting process and painting process.
Uses: The coating made of zinc phosphate preparation has excellent anti-rust performance and water resistance. It is used to prepare various water, acid and anti-corrosion coatings, such as ships, automobiles, industrial machinery, light metals, household appliances and metal containers for food. Rust paint. It is also used as a base material for alkyd, phenolic , epoxy resin and other coatings , as well as a flame retardant for chlorinated rubber and synthetic polymer materials .
