Zinga is a one-component anti-corrosion zinc coating system. 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. This website is the primary source of information relating to the Zinga range of zinc anti-corrosion products.
Please take some time to browse the site and download all the relevant Data Sheets. If you have any further questions relating to your particular Application please do not hesitate to Contact Us.
Zinga is the mainstay of the product range and is the principle subject of this website. Zinga is available in 1, 2, 5, 10 and 25 kg tins aswell as in spraycans (Zingaspray). Although highly versatile it is not able to solve every problem so for particular applications there are other products within the range that can help. Zingasolv is the recommended thinner to be used with Zinga when spraying. It can also be used for cleaning when using Zinga.
Aquazinga is a water based two component zinc silicate. It is considerably harder than Zinga and is able to resist much higher temperatures, up to 600C. Also Aquazinga has a much higher tolerance for hot oils and chemical attack and is ideally suited for use on refinery hardware. However, unlike Zinga, Aquazinga requires a dry surface for application and is less flexible under bending loads. Aluspray is a finishing coat which only comes in spray cans. When applied to Zinga it gives a satin finish of pure aluminium and is solely used for aesthetical purposes.
Zingalu Spray is a cross between Zingaspray and Aluspray containing a small amount of aluminium but still consisting of predominately zinc. It provides a brighter finish than Zinga but offers slightly less corrosion protection. Alufer N is a single component polyurethane intermediate coat which can be applied over Zinga or Aquazinga to provide vastly increased chemical resistance. Alufer WR is very similar to Alufer N but is a topcoat which has been designed to resist ultraviolet weathering as well as chemicals.

It cannot be stressed strongly enough that the key to Zinga's long life is in the thorough preparation of the steel substrate to the correct specification. Please always follow the appropriate Zinga UK specification in conjunction with the Zinga Application Data Sheet although the following gives a general guide.
Firstly the surface will require to be decontaminated by steam cleaning or high pressure washing to completely remove salt, grease, old paint, loose particles etc.
With marine structures, all crustacean growth must be removed from the steel's surface before the degreasing process begins, and not after.
If the Zinga is to be applied to old, worn galvanising, metallising or old Zinga then all that is required after decontamination is to ensure that there are no loose particles on the surface. Please contact Zinga for a full specification. Read More
Zingametall in Belgium supply an unlimited shelf-life guarantee for the Zinga in an unopened container stored at room temperature and away from sources of moisture.
The production process is regularly inspected by the BBA (British Board of Agrement) and SGS (Societe Generale de Surveillance) in order to ensure that the product does at all times meet the pre-defined standards. As a result of the above, Concordia are able to provide product liability insurance against physical, material and immaterial damage. This policy basically insures the quality of the Zingametall products but does not apply in case the damage is caused by, for instance, a wrong application or insufficient surface preparation.
For complete peace of mind the user can subscribe to an optional Insurance Backed Guarantee via SGS Axa-Med (www.sgsaxamed.be). They will inspect the individual projects and, if approved, write a suitable specification and scrutinise the whole process from surface preparation onwards. The period of the guarantee is dictated by the chosen insurance underwriter and is dependent on the type of project, environment etc. The cost of this cover typically represents 4% of the total Zinganisation costs.
