Zinga Zinc Spray 500ml

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.
Zingaspray is a 500ml aerosol which has all the advantages of the original Zinga in an easy-to-use spray can. One coat of Zingaspray will dry at approximately 20-25 microns, so a minimum of two coats is recommended. Zingaspray can be used for repairing galvanising or products previously treated with Zinga. Ideal for touch-up work and for small areas where it can be difficult to get to with a brush or a roller.

Zinga is an active zinc performance coating which works in conjunction with the metal beneath, whereas paints are passive barriers. Regardless of how thick paints are applied, they remain as barriers. Once they are breached corrosion sets in immediately. Despite this significant difference Zinga is still often mistaken for a paint simply because it’s liquid and comes in a tin. But there are other more subtle differences. For example it does not skin over in the tin because Zinga has an unlimited pot-life and it doesn’t go tacky like a paint.

Cathodic protection, or active 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. Other well established methods of cathodic protection include hot-dip galvanising (HDG) and zinc thermal spraying both of which exhibit a constant sacrificial rate of the zinc layer.
