The development path of metal pretreatment, the development of ceramic agents has triggered a major revolution!

With the development of the times, metal materials are increasingly used in our daily life and industry. For example, steel requires pretreatment processes such as degreasing and rust removal before coating. Then, a chemical conversion film is formed on the metal surface through chemical treatment methods to protect the base metal, enhancing the adhesion of the coating and the corrosion resistance of the metal to some extent. Currently, most processes use phosphating technology. However, with the continuous promotion of energy saving and emission reduction, traditional phosphating can no longer meet modern environmental protection requirements. The application of ceramic conversion agents has brought a significant change to the chemical film formation technology on metal surfaces. The new type of phosphate-free conversion film (ceramic conversion film) is quietly replacing the traditional phosphating film.

The application of ceramic conversion agents has brought a major transformation to the chemical film-forming technology on metal surfaces. The new type of phosphorus-free conversion film (ceramic conversion film) is quietly replacing the traditional phosphating film.
