TDZ Technology

Best Solution Zinc Coating For Metal Products.

What Is TDZ Technology?

TDZ Technology is one kind of zinc coating which is an enhanced and patented development of the galvanizing technology well-known for more than a hundred years. Based on heat up distribution way of zinc coating, the metal will be highly stainless.
The basis of TDZ is a zinc coating technology at several levels of penetration into the metal.
Thus, TDZ technology is an integral unit with the component, but not only with the surface layer, like the other known types of zinc coatings.

The Advantages Of Using TDZ Technology

  • Does not change the texture of the item surface
  • The coating is applied under strictly controlled temperature. Minimum temperature of coating 320C. This allows to coat every items without affecting their mechanical properties
  • Does not require additional machining after coating
  • High adhesion to additional types of coating such as any type of paint or passivator, if necessary
TDZ is a new environmentally friendly technology of thermo-diffusion zinc coating: DiAv-93
