Characteristics – Advantages




ZINGA Galvanising Is Easy To Apply On Site

Once thoroughly mixed, ZINGA can be applied by using a normal paintbrush, a short-fibre roller (not for the first coat) or a conventional or airless spray-gun.

ZINGA can be applied in a wide variety of weather conditions.
The application surface temperature range is from -15°C to +40°C where conditions allow with a maximum humidity of 95% so long as the dew point is 3°C minimum above the steel temperature.
 


ZINGA For Faster Drying Time And Job Turnaround

ZINGA has one of the fastest drying times in the coating industry. It is touch dry in around 10 minutes at 20°C (40 µm DFT). ZINGA can be recoated with a new layer of ZINGA 1 hour after touch dry (by pistol, after 2 hours by brush), and with other paints 6 to 24 hours after touch dry.

 


Zinga Galvanising Does NOT Peel Off And Is Not Brittle

ZINGA is not a paint and does not behave like a paint. When a paint is damaged, it will cause a layer of paint to ‘chip off’ or ‘peel off’. Also when damaged with a hammer, a paint will suffer from the impact which causes severe stress on the binder of the paint causing the paint to show cracks. These cracks are the weak part of the paint through which moisture and water can seep leaving the steel exposed to the environment and rusting occurs.

ZINGA does not act like that, it acts more like the steel below: when impacted with a hammer, the Zinc is merely pushed away, bending along with the steel.

Therefore, ZINGA can also be bent with the steel to a certain extent.


Recharging

One of the most decisive advantages of ZINGA is that it can be recharged. Each new layer of ZINGA makes the former layer liquid, so as to form a new homogenous ZINGA layer. There is no risk for accumulation of layers that are different in structure, which could cause peeling off. The surface preparation before recharging is reduced to a minimum: you only need to remove the Zinc salts of the surface. Depending on the age of the ZINGA layer, and environmental conditions, this can be performed with a water wash, preferably by steam-cleaning at 150 bar at 80°C or by sweep blasting (very light blast).

 


Zinga Galvanised Steel Can Be Topcoated Any Colour With 2k Coatings or Powder Coating

If ZINGA is used as part of a duplex system i.e. it is overcoated with a compatible paint system, the topcoat provides the initial barrier to the elements, but the zinc oxide will still form a secondary barrier if the outermost layer is compromised in any way.

As the paint topcoat naturally begins to break down and becomes porous over time, the ZINGA fills the pores from below with zinc oxides enabling the top coat to last longer.

Additionally, ZINGA does not even start to sacrifice itself until the topcoat has become damaged to the point where it is exposing the bare zinc to the elements.

It is because of this that we can state that the service-life of a duplex system can be 50% more than the sum of the individual lives of ZINGA and the paint topcoat when added together.


ZINGA Galvanising Fire Retardant Properties

A ZINGA unique system shows fire retardant properties. Moreover, it does not spread flames or produce toxic flames. This has been tested by two independent laboratories.
A fire test at SGS Yarsley Technical Service (UK) found that ZINGA has a class 0 surface (best ranking) in flame spread ranking.

A reaction to fire test was performed at Efectis (Netherlands) in 2013. ZINGA showed to propagation of the fire, no toxic smoke or droplets.

Both test results can be found here.


Zinga Galvanising Can Be Welded Over

ZINGA Galvanising is one of the few that can be welded and applied over welds.
The welding of steel coated with ZINGA film galvanising (max. 60 μm DFT) is possible without excessive zinc fumes because the heat of the approaching weld bead burns off the organic binder well below the melting point of zinc.
