The zinc coating is carried out in closed chambers. The thermal diffusion process allows the application of layer thicknesses between 20 and 120 µm, which are ideally suited as substrate layers for subsequent painting. The smooth surface has significantly better wear resistance and corrosion resistance than what could be achieved with hot-dip galvanizing.
The zinc thermal diffusion process - in combination with CDP coating, wet painting or powder coating - allows the creation of a highly corrosion-resistant surface in almost any color.
ZTD Coat® is a special corrosion protection coating which thermally modifies the surface of a wide variety of components using the patented zinc thermal diffusion method. The resulting protective layer forms a strong bond with the carrier material and thereby ensures excellent long-term corrosion protection.
ZTD Coat® is used primarily in the automotive industry and anywhere where excellent corrosion protection must be combined with other functional and decorative properties. Impreglon fulfills all specifications of international car manufacturers.
