Zinga Film Galvanizing System, a Material that Offers an Alternative View on Corrosion

Zinga is a one-component anti-corrosion zinc coating system which contains a minimum of 96% zinc in the dry film. Its unique formula provides environmentally safe cathodic protection to steel comparable with hot-dip galvanising, with the added advantage that it can be applied as though it were a paint. Zinga has unlimited shelf and pot life, easy to apply, able to reload and re-coatable. Zinga film galvanizing system is nontoxic (BS 6920), mechanically flexible, not brittle, doesn’t peel off and UV resistance. Atmospheric temperature resistance for Zinga ranges from -40˚C to 150 ˚C with peaks up to 180 ˚C.

 

Cathodic 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 chemical reaction. In this way the protection of the metal is guaranteed, even when the zinc layer is slightly damaged.                 With Zinga, the sacrificial rate reduces dramatically after the zinc layer has oxidised and the natural porosity have been filled with zinc salts. Additionally the zinc particles within the Zinga layer are protected by the organic binder without adversely affecting the electrical conductivity. This enables Zinga to create nearly the same galvanic potential between the zinc and the steel as hot dip galvanising but with a lower rate of zinc loss because, put simply, the binder acts as a "corrosion inhibitor" to the zinc.

Zinga film galvanizing system is compliance to ISO 12944. It is now available globally in more than 50 countries for on-site galvanizing of steel work in power stations, bridges, transmission towers, crash barriers, cement plant as well as rebars.

Zinga , film galvanizing system, tested according to standards ISO 12944, is now available globally in more than 50 countries for on-site galvanizing of steel work in nuclear power stations, bridges, transmission towers as well as rebars. It is used also for re-loading of old hot dip galvanized on power transmission pylons, crash barriers and other structures

Zinga , film galvanizing system , a material created to solve a specific problem, now has found wide usages in various fields. This means it could also help you to solve your particular corrosion problem.

 

The zinc in Zinga becomes the sacrificial anode in relation to the steel but it corrodes at a much slower rate than would otherwise be expected"
