NOVA ZINC is a new scientific composition of pure zinc powder (99%), resins and other components. Applied to ferrous metals and aluminium it forms a tough but flexible zinc metal film, which by electrochemical action offers excellent protection against corrosion, even when the coating is scratched or worn down.
There is an essential difference between NOVA ZINC and paint. Paint and primers protect by forming a “skin”.
NOVA ZINC however gives protection against corrosion by the galvanic action between zinc and iron. Electrochemically expressed : under the influence of water vapour and oxygen the zinc powder works as an anode and the metal under it as a cathode. Cathodic protection. Corrosion affects only the zinc and not the base metal.
When a paint skin is damaged, corrosion will appear and will also run under the undamaged paint. If the NOVA ZINC coat gets damaged then unsoluble alkaline products (zinc salts) will be formed. In other words the injury recovers itself and thus continues protecting the suface further against corrosion, as opposed to paints and primers.
