Surface treatment overview
Surface treatment is a process for artificially forming a surface layer on the surface of a base material that is different from the mechanical, physical, and chemical properties of the base body. The purpose of surface treatment（E-coating/KTL） and finishes is to meet the requirements of product's corrosion resistance, wear resistance, decoration and other special functions.

KTL surface treatment
KTL provides products with long-term anticorrosion, high resistance to mechanical damage, salt water resistance and chemical resistance.

During the KTL process, the product is completely immersed in a liquid-colored KTL bucket, soaked through an anode and placed on both sides and bottom of the KTL, and charged with a positive electrode.

In this process, the immersed product is connected to the negative electrode and acts as the cathode.

KTL is used as the final coating or primer under the paint and is suitable for all products and their initial sandblasting, providing the highest quality surface treatment.
