What is Zinc Flake Coating?
Zinc Flake Coating is a high-performance corrosion protection system based on a unique chemical formulation. These coatings are used to protect non-flexing or rarely- flexing parts like brake rotors, drums, callipers, brake lines, hose clamps, fuel tanks, clips, fasteners, springs, seat belts, door lock components and pretty much anything else that comes in contact with the elements and can survive a 450-degree curing cycle. These coatings can also prevent galvanic corrosion as a result of dissimilar metals coming in contact with each other.

How it works?
Discover the efficiency of Green Cotech’s coating process, where cutting-edge technology meets expertise to provide superior protection.
Barrier effect
The positioning of the zinc flakes gives the film a barrier effect that isolates the metal from the corrosive environment. Indeed the flake morphology increases the length of the path that the aggressive substances must travel to reach and corrode the substrate.
Sacrificial protection
When steel is coated with zinc flake, cathodic protection is achieved. Because of its lower electrochemical potential, compared to iron, zinc oxidizes preferentially: it “sacrifices” itself to protect the steel substrate.
Self Healing
The cathodic protection of zinc produces various kinds of salts (oxides, hydroxides, carbonates…), also known as “white rust”. Thanks to their mobility and adherence properties, these compounds heal the damaged areas of the coating and therefore act as a corrosion inhibitor to protect the substrate.
Adhesion to substrate
Our zinc flake sol-gel binders create strong covalent bonds with the substrate, which ensures excellent adhesion. In addition, at the interface, the migration of corrosion precursors (O2 and H2O) becomes more difficult, which reinforces the barrier effect of the coating.
