Product Description

Zinga is a unique system which can be used as an alternative to hot-dip galvanisation or metallisation.

Zinga Film Galvanising System is a single pack coating that contains 96% zinc to provide cathodic protection of ferrous metals. Zinga can be used as an alternative to hot-dip metallisation, as a primer in a duplex system (active and passive) or as a recharging system for hot-dip galvanisation, metallisation or zinganised surfaces, Zinga can be applied on site, avoiding the need for dismantling ferrous metal structures, forming a grey matt, non toxic finish. Zinga conforms to ISO standard 3549 in regard to its zinc purity of 99.995% and to ATM standard A780 in regard to its use as a repair coating for hot-dip galvanisation. Zinga can be overcoated with a compatible paint.

Best Uses

Use Zinga for the protection of ferrous metal structures such as bridges, a primer for boat keels, pylons, masts, street furniture, etc.

As the paint top-coat naturally begins to break down and become porous over time, the Zinga fills the pores from below with zinc oxides enabling the top coat to last longer. Additionally, Zinga does not even start to sacrifice itself until the topcoat has become damaged to the point where it is exposing the bare zinc to the elements. It is because of this that we can state that the service-life of a duplex system can be 50% more than the sum of the individual lives of Zinga and the paint topcoat when added together.


Promain are currently looking for contractors who would like to become approved applicators of the Zinga range of products who can also provide suitable preparation facilities via wet abrasive blasting through machines. If you and your company are interested, please contact our technical team on 01462 421333 or email us via the contact us page.

Zinga can be applied by brush, roller, conventional spray gun or airless spray after thorough preparation of the substrate. The substrate should first be degreased, preferably by steam cleaning, then gritblasted or slurry-blasted to cleanliness degree SA 2.5 according to ISO standard 8501-1:2077 or to cleanliness degree described in standards SSPC-SP10 and NACE No.2. The surface must be free from rust, grease, oil, paint, salt, dirt, mill scale and other contaminants. Apply Zinga as soon as possible after preparation to a dry surface. ZINGA must be thoroughly mechanically stirred to achieve a homogeneous liquid before application. After a maximum of 20 minutes, re-mixing is necessary. 

For overcoating this product, use Rustoleum Pegalink as a sealer coat prior to applying your chosen topcoat. Please note, that the application of a alkyd directly onto Zinga is not possible as the alkyd will not fully dry or cure.

Clean brushes and spray equipment using Zingasolv. If purchasing this product you will need to purchase Zingasolv as well.

How Does It Work?

Cathodic protection arises from the anode, sacrificing itself in favour of the base metal, which allows the resulting flow of electrons to prevent the chemical reaction of the corrosion. This means that the protection of your metal is guaranteed, even when the zinc layer is damaged slightly. When you use Zinga, the sacrificial rate is reduced 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 negatively affecting the electrical conductivity of the metal. This allows 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 due to the fact that the binder acts as a sort of 'corrosion inhibitor' to the zinc.
