The unique characteristics and advantages of ZINGA:

1) ZINGA protects the metal against rust in two ways: an active, cathodic, galvanic protection due to its high zinc content and a passive barrier protection due to the zinc salt on top of the surface, and due to the binder in ZINGA that reduces the disintegration of the zinc.

2) The application of ZINGA is very easy. It can be painted onto the surface with a brush or a roll. It can also be sprayed with a pistol, and it can be applied in a bath. There is no need for sophisticated equipment that can only be found in a workshop. ZINGA can be applied on site, even by non-professionals.

3) ZINGA can be applied in a wide range of weather conditions. ZINGA can be applied on a damp surface (but not on drops of water). Humidity can even intensify the cathodic action and accelerate the formation of the zinc salts on the surfaces that offer the barrier protection. ZINGA can be applied at very high or low temperatures (up to 40° C or 104° F and down to -15° C or 5°F).

4) The surface preparation can be reduced to a minimum: the metal must be clean (free from dirt, grease, oil, salts, paint, and mill scale) and rough. It is not always necessary to grit-blast the metal first.
Application on bare metal: Mostly grit-blasting is necessary, but in some cases the substrate already has the required roughness degree due to former grit-blasting or due to corrosion.
Application on top of hot-dip galvanization: Old and corroded hot-dip only needs to be cleaned and already has the required roughness degree. New hot-dip can be treated in order to obtain the required roughness.
Application on an old ZINGA layer: When ZINGA is applied on an old ZINGA layer, then the surface just needs to be cleaned.

5) ZINGA is always applied under ambient temperatures, so that delicate metal structures cannot be deformed. Even dipping is done in ambient temperature. No energy is wasted to warm up ZINGA, which is necessary for hot-dip galvanization wherefore you need temperatures up to 460 °C.

6) ZINGA has a quick drying time. A new layer of ZINGA can be applied after 1 hour. Topcoats can be applied after 6 to 24 hours, depending on layer thickness and atmospheric conditions.

7) ZINGA does not peel off and is not brittle. In case of mechanical damage the ZINGA layer will be compressed or squashed, but it will not crack due to its flexibility.

8) One of the most decisive advantages of using ZINGA is that the ‘zinganization’ system can be recharged. Each new layer of ZINGA blends perfectly with the previous one. Additional layers all blend to one single, homogeneous ZINGA layer. There is no risk for accumulation of layers that are different in structure, which could cause peeling off. You cannot distinct different layers, as is the case with galvanizing by hot-dip. Moreover, this capacity of recharging reduces the surface preparation to an absolute minimum. Other coating systems, for instance with paints, demand an elaborate and often expensive surface preparation before the application of a new layer.

9) This property of recharging can be of use if you still have to do some drilling or welding on the surface, or if the structures still have to be transported. In that case the first layer is meant as a primer. It can intercept possible damages. Even welding is possible on top of ZINGA. Afterwards, the final layer of ZINGA can be applied and local damages can be repaired. The new layer makes the former layer liquid again and the result is one homogeneous ZINGA layer. When there is no need to re-coat the whole structure, you can apply a small quantity of ZINGA on the damaged spots and the whole structure is free from rust again. Repairs will be invisible after a certain time.

10) Structures that have been ‘metallized’ or galvanized by hot-dip will begin to rust after a certain period. Such worn-out and damaged structures can also be recharged by ZINGA.

11) ZINGA has a zinc content of 96 % in the dry layer. The zinc is pure to 99.995%. In order to obtain a real cathodic protection you need at least 92 % of zinc in the dry layer. That is scientifically proven. The so-called zinc-rich paints do not meet this condition.

12) Moreover ZINGA is based on protected zinc. The zinc particles are protected by a special resin that allows the formation of the galvanic couple, but that also gives an additional protection. Therefore protection with ZINGA is a superior alternative for galvanization by hot-dip.

13) The zinc granules have been specially shaped so that they have a bigger contact surface through which they can attach to one another. For your information: the zinc used in ZINGA is made by the Belgian company Umicore, well-known all over the world, since they are the number 1 manufacturer in the world of these atomized zinc dust pigments, further electronically prepared for Zingametall. This atomization process provides unique qualities and a very high zinc purity. This is also one of the reasons why ZINGA does not have one single true competitor in the world.

14) ZINGA is uniquely characterized by the fact that it sacrifices itself or that it is “consumed”. Together with the quality of not peeling off, this results in the depletion of each applied layer: between 2 – 15 μm per year depending on the environmental conditions. This is an important factor in monitoring the application and the evaluation of the lifetime of the system. Hence, it is a true benefit in terms of maintenance and budget scheduling.

15) With ZINGA, a customized and personal solution can be offered. Customers are not always in need of a long term corrosion protection or don’t have the budget for it. In case of a limited budget and desired protection time of for instance only 5 – 7 years, the layer thickness can be reduced and this will have an effect on the price per m². In other words: ZINGA is the most “flexible” customized solution.

16) ZINGA can be top-coated by a large number of compatible paints. Such duplex systems will more than double the lifetime of ZINGA. In order to reinforce the duplex qualities of the ZINGA system a topcoat can be applied. We can supply you with different compatible paints: acrylic, epoxy, polyurethane; with or without micaceous iron oxides, the so-called MIO’s. These paints can be applied directly on ZINGA (using the mist/full coat technique).

17) These topcoats can be bought from the same supplier. You just need to speak to one contact person and only that one company can be held responsible for the total application.

18) ZINGA is composed of non-toxic elements according to European Standards and can be used in contact with potable water.

19) ZINGA is heat resistant up to 120° C. ZINGA can also intercept occasional and short thermal-shocks up to 150° C.

20) ZINGA has an unlimited pot and shelf life. ZINGA is a one component coating.
