USE

ZINGA is used as a primer and/or finishing coating as protection against corrosion of metallic structures. Itis also used for maintaining and repairing galvanised, zinc-sprayed or zinganised structures.

Appearance/Composition

ZINGA is a one-pack compound containing 96 % of electrolytic zinc dust (pure to 99.995 %). The coating also contains synthetic resins, pigments and solvents. The composition of ZINGA cannot be compared to zinc rich paints or other one-pack products. The purity of the used zinc is such that ZINGA contains no lead or cadmium, nor does it contain toluene, xylene, benzene, methylene chloride, nor methyl-ethyl-ketone (M.E.K.). After application ZINGA cures to a dry layer, containing a minimum of 96 % zinc.

Preparation of the surface

– New smooth surface : Sandblasting Sa 2.5 is necessary to take away mill scale and to obtain a roughness degree Ra 12.5µm Rz 50-70µm .
– Old, galvanised or rusty surface : Remove loose particles and degrease (steam, degreaser…).
– Painted surface : Remove paint by sand or grit­ blasting, high-pressure water jetting or any chemical pickling process.

In short : The surface must be free from mill scale, oil, paint and grease. ZINGA can be applied on damp surfaces in moist conditions. A little rust does not prevent the use of ZINGA.

Handling

ZINGA is not hazardous according to European standards. The manufacturer recommends that the usual safety precautions for paint work should be taken.

Drying Time

ZINGA is touch-dry and dust-free in about 10 minutes, depending on the atmospheric conditions and the drying process. It is mechanically cured after approximately 48 hours. ZINGA continues to harden further when exposed to humidity and indirect sunshine (ultra violet rays).
ZINGA is a coating that is best applied in two layers. A new coating of ZINGA can be applied after one hour. In a duplex system, topcoats can be applied after 6 to 24 hours (depending on the drying process).
