Brief introduction of ceramic coating agent system

Because the steel (iron) materials (such as stamping) in the molding process will inevitably in the formation of a layer of film covering complex iron surface, this layer mainly contains oil, lubricant, cutting oil, rust, stains, fingerprints, they will lead to poor appearance, surface corrosion resistance, a series of the problem of non-compliance spray coating adhesion, seriously affected the subsequent anticorrosion and decorative work (such as: coating, spraying) effectively. Therefore, it is imperative to carry out surface treatment (such as phosphating) for the iron workpiece (cold ligation plate, galvanized sheet, etc.).

However, with the increasingly stringent environmental requirements, the traditional phosphating process, such as phosphorus, nitrite, nickel and sediment treatment, has gradually failed to meet the needs of modern environmental protection. The new generation of phosphorus free environmental conversion process (pottery treatment) came into being. The technology can form nanoscale film on some metal surfaces, enhance coating adhesion and corrosion resistance, and can deal with steel, zinc, aluminum and alloy materials. It is an excellent alternative to traditional phosphating process.
