Zinc thermal diffusion

Zinc thermal diffusion isa state-of-the-art corrosion protection process of premium quality in which the surface of the material is thermochemically modified. The resulting protective layer forms an extremely strong bond with the carrier material and thereby ensures excellent long-term corrosion protection. Thermal diffusion zinc coating is an environmentally friendly process without the use of chromium VI.

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.
