TEST ON MARINE BUOYS

Two sea buoys have been floating in the Atlantic Ocean for 4 years (very corrosive environment). A mild steel buoy treated with ZINGA (yellow buoy) was compared to a buoy that was galvanised by the traditional hot-dip procress (green buoy). The two buoys had received the same type of topcoats with the same layer thickness, with a supplementary adhesion coating for the hot-dipped buoy

Results: ZINGA shows no trace of rust. Hot-dip is severely corroded in several places.

Conclusion : Zinganisation is much more effective than the hot-dip process.

BRIDGE TREATED WITH ZINGA

The Kalvoya bridge situated in Baerum, Norway, was completely treated with ZINGA in 1985. On the steel carrying cables, ZINGA was applied by painting gloves between the cable-strands. The whole structure had a coating of 120 µm applied (controlled by the bureau Det Norske Veritas).
The only maintenance that was n cessary after 10 years was minor repairs due to mechanical damage from accidents. Only 5 kg of ZINGA was needed for the total repair of the bridge. This proves the long-term protective properties of ZINGA. It was not even necessary to blast the surface,which considerably reduced the cost of surface preparation. Using ZINGA is saving on maintenance.

INDEPENDENT TEST RESULTS

Independent laboratory tests on ZINGA have been conducted at the University of Ghent (Belgium), B.N.F. Fulmer Material Technology Oxfordshire (U.K.) as part of the B.B.A. programme (British Board of Agrement), F.M.P.A. (Forschungs- und Materialsprufungsanstalt, Germany), Laboratorio General de Ensayos y de Investigaciones Barcelona (Spain), P.S.B. (Productivity and Standards Board, Singapore), S.A.B.S. (South African Bureau of Standards), COT bv (testing lab according to ISO 12944) and many others. Full details are available on request.

Field tests have demonstrated that ZINGA outperforms any, other zinc coating in different aggres ive circu stances all over the world : U.S. A’r my, Val Reefs goldmines (South Africa), Service Maniti”me Departement de Ia Vendee (France).

A dry Jayer of !ZINGA is non-toxic as tested with potable water following the W.R.C. tests of effect on water quality (B.S. 6920). ZINGA has a zero surface spread of flame according to B.S. (fire retardant class Al).
