Bonderized steel strip with zinc phosphate coating
We can finish our cold rolled steel strip grades with a zinc phosphate coating on request. This coating is chemically bonded to the surface of the strip and forms a crystalline layer with cavities and capillaries. This results in an enlarged surface that serves as an ideal basis for a wide range of processing and finishing steps. The zinc phosphate coating is the perfect adhesive primer for further varnishes or coatings. In addition, it can serve as a lubricant reservoir for soaps, oils, or greases. The latter is particularly appealing when you require materials with increased strength but still need to form them into the final product. In combination with a lubricant, the zinc phosphate coating reduces friction during forming operations, making complex, multistage forming processes involving harder materials possible. Last but not least, the zinc phosphate coating also helps significantly reduce tool wear.
