Prime Zinc and Super Zinc high performance zinc spray and liquid compounds protect steel through galvanic action giving triple anti-corrosion help to galvanized products.
First generation zinc barrier dries fast, protecting metal against corrosion.
Oxygen in the air reacts with the resin forming a hard, highly resistant layer.
Long Term Protection:
The second generation of zinc is formed in the external layer of the surface in reaction with humidity and air, forming zinc oxide, a coating that is insoluble, thus protecting the metal in the long term.
When zinc and steel are in direct contact and they are separated by a scratch and are in contact with moisture, zinc becomes anode and steel cathode, resulting in zinc being sacrificed by the steel forming more oxide layer of zinc.
