Dipping
Zinga can be used in dip-tanks for fast application onto blast-cleaned or phosphated steelwork. Where the steelwork is to be phosphated, it must have a minimum weight of 1200 - 1500g/m2. The viscosity of the liquid zinc in the tank will determine the final dried film-build of the zinc layer.
Items can only be dipped once, and never double-dipped, as this causes slight waves on the zinc surface.The zinc can be force-dried in either low-bake ovens @ 40degrees C or in a standard powder-coat oven @ 180 - 200 degrees C. Short-wave infra-red ovens dry the zinc-film in 2 minutes.
After dipping in the zinc tank, articles can be sent straight through the oven without waiting for a flash-off period. Once the dried Zinga-coated items leave the oven and cool down to below 50 degrees C they can be coated with powder or wet paints.
What Is Zinga?
Zinga was originally invented in Ghent University, Belgium, in the 1970's and has since been used in a wide variety of projects throughout the world...
HOW ZINGA WORKS
Cathodic protection, or active protection, arises from the zinc (the anode) sacrificing itself in favour of the base metal (the cathode) with the resulting flow of electrons preventing corrosion's...
