Cataphoretic coating (KTL)

Cathodic immersion coating (KTL) is based on electrochemical properties of individual materials. The physics of the process are based on the fact, that materials with different charge are mutually attracted, which results in high adhesion. The cathodic immersion coating technology can be used for applying an even protective layer on metal surfaces and cavities in an evenly thick layer with excellent surface quality.

Surfaces with the KTL treatment make an ideal base for powder coating or ordinary painting. The KTL can be used almost any time, regardless of the surface colour or structure.
