What are Oxidation chemicals?

Oxidation chemicals are also called as oxidation salts or blackening salts. Oxidation treatment forms a dark colored corrosion resistant coating on iron, steel and die castings. After coating, metal parts go into protective lubrication for enhanced corrosion protection. Lanpa oxidation chemicals could be devided into three main series, room temperature series, high temperature series, and remaining heat series. Customers could choose the suitable products according to their own process lines.
