About Zinga Cold Galvanising Paint

What is Galvanizing?

Galvanization or galvanizing (also spelled galvanisation or galvanising) is the process of applying a thin protective layer of zinc to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the components are submerged in a bath of molten zinc. Alternatively, a layer of zinc can be applied by brush, roller or spray. This is carried out with a paint called Zinga. Zinga is a cold galvanizing paint that test show will offer greater protection against rust over hot dip galvanizing. corrosion of zinc is much slower than steel or iron therefore the life of the metal can be dramatically extended. Due to the alloying of the Zinc to the iron, cathodic protection is achieved. Previously hot-dip galvanized steel can simply be over coated with Zinga but any rust should be removed by mechanical means before application. Galvanized steel resistance to rust corrosion depends largely on the thickness of the protective galvanized zinc coating that is applied , we strongly recommend at least 2 coats of Zinga are applied allowing the paint to dry between coat. Galvanized steel will last in excess of 25 years but factors such as high humidity, above 60% and attack from de-icing salt used on highways.

Zinga's galvanizing paints unique formula provides environmentally safe cathodic protection to steel. Zinga cold galvanizing paint is comparable with hot-dip galvanising, with the added advantage that it can be applied by brush roller or spray as though it were a paint.

Zinga 96% Cathodic Protection has provided durable protection to a multitude of complex steelwork projects throughout the globe. Some of the well known architecture protected in Zinga include the Bird's Nest stadium in China, the Koisk Louter in Ghent, Runcorn Energy Plant in the UK, Guangzhou Baiyun International Airport and Mumbai Domestic Airport. Zinga is also approved for London Underground use for the protection of steelwork.

Zinga galvanizing paint is also suitable for the protection of boat hulls, electricity pylons, off shore oil rigs, power stations, pier legs, bridges, water turbines, car chassis', airport exteriors, tanks and more. We have a huge range of case studies available - click here to see Zinga projects on our Knowledge Hub.

Promain are proud to supply the full range of Zinga cold galvanizing paint products as a quality, durable alternative to hot dip galvanization. To read our full Zinga paint review listings, view each individual product below.

A Guide to Zinga

If you’re new to Zinga, there’s a few things that you’ll need to know, we’ve put together some quick-fire questions for you to answer. For more information, you can contact our technical team who will be more than happy to assist with any more queries that you may have.

What is Zinga?

Zinga is a 96% pure zinc coating.

Is Zinga paint?

No, Zinga is a liquid but it is not paint and it doesn’t behave like paints. It doesn’t run, skin over or clog up spray guns. It doesn’t go blotchy or stay tacky like paint can. Zinga tins can be stored indefinitely unopened and once opened they can be stored until you next need it, so that there’s no wastage.

Does Zinga contain solvents?

Yes but the blend doesn’t contain any of the extremely toxic solvents, such as benzene, xylene, toluene, MEK, methyl-chloride, many of these are found in industrial solvent blends. Zinga is rated totally non-toxic when dry.

What can Zinga be compared to?

Hot-dip galvanising and zinc thermal spray (TSZ), in a marine environment Zinga consistently outlasts hot-dip galvanised steel.

How does Zinga work?

Zinga contains a high concentration of active zinc, this provides a potential difference of around -840mV between the coating and the substrate. Once the steelwork becomes wet, the zinc ions go into dissolution and the current will begin to flow from the zinc to the steel. This depletes the zinc layer and protects the steel underneath by preventing any corrosion reactive taking place, this is called galvanic protection.

If the Zinga gets scratched what happens?

Zinga has a 3-5mm throw, this means that any uncoated metal within 5mm from the Zinganised surface, such as a scratch, will be protected. A layer of rust will form, but there won’t be any pitting beneath it, small scratches and chips will often go light brown-grey in colour but there won’t be any corrosion underneath.

Will you get rust creep under Zinga?

No, this is due to the steel that has been coated, it will have a galvanic charge flowing through it between the zinc and the steel, so there’s no way for the corrosion reaction to start under the Zinga.

What’s the lifespan of Zinga compared to HDG?

After comparative usage on marine projects, Zinga out-lasts Hot Dip Galvanising by approximately 10% in normal atmospheric conditions, the 2 coatings are comparable in lifespan.

In Zinga fireproof?

Yes, it is certified to BS476 parts 6 and 7, Zinga will not propagate a fire or cause spreading which is why it has been used on the London Underground for a number of years, it’s increasingly being used on offshore oil platforms and is also approved for use by the British Navy, as well as being used on vessels such as the HMS Defender.

Can Zinga be used around food?

Not when applying Zinga, but when it is dry, yes it can. Zinga is medicinal quality zinc (99.995% pure) so once dried it is completely safe to use in areas where food is to be prepared or stored. The binder is completely non-toxic and completely safe when it’s dried, it’s recommended that a thin layer of an FDA-approved paint is applied on top of the Zinga as the Zinga is slightly porous, this means that there’s a possibility of bioaccumulation where bacteria could live.

Can you use Zinga where abrasion has occurred?

Yes, Zinga has been used to galvanise chains and bolts for marine use, it has been subjected to abrasion and it seems to take on shine and polishes up.
