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 tests 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 coats. Galvanized steel will last in excess of 25 years dependant on factors such as high humidity, above 60% and attack from de-icing salt used on highways.
