A one pack zinc rich Cathodic protection primer, contains 96% Zinc in the dry film.
When suitably cleaned steel is dipped in molten zinc at 450°C, a coating comprising of a series of iron/zinc alloy layers, over-coated with relatively pure zinc is formed. The hot dip galvanized coating provides a barrier against corrosion and sacrificial protection. When the hot dip galvanized steel is site cut, welded or mechanically damaged it loses these properties. In order to prevent this sacrificial protection property prematurely consuming the surrounding coating, repair of the damaged coating/area using ZincFix® ZincDek 90 is recommended.
ZincFix® ZincDek 90 oxidises and a layer of zinc salts slowly builds up on the surface creating a barrier effect, diffusing water and air.
The ZincFix® ZincDek 90 binder inhibits the depletion of Zinc, providing a long lasting combination of active & passive protection which blocks the corrosive
elements from reaching the steel.
The ZincFix® ZincDek 90 sacrifices itself, protecting the steel beneath. Upon impact the electron flow resulting from chemical reaction between zinc, oxygen, water prevents oxidation of metal.
