Zinga is a one pack zinc coating system that can be applied by spraying, rolling or brushing. It is also available in spray cans. Zinga is safe because it contains no known carcinogens and is totally non-toxic in its dry state.
Salt-spray tests and experience from the field have shown that Zinga lasts up to 10% longer than HDG in marine or saline environments due to a slower rate of zinc loss. Please see testimonial from La Direction Departementale de l’Equipement, Service Maritime (France) for field experience or the Fulmer report or the PSB report for lab tests. In industrial or normal atmospheric conditions Zinga lasts as least as long as HDG as can be seen in the report on the Schwenk cement factory in Germany.
Zinga can be applied in a workshop but it can also be applied on site. Metal structures do not have to be dismantled before treatment which would be necessary with hot-dip galvanising.
Zinga can be used to re-coat worn hot-dip galvanised or zinc thermal sprayed surfaces in order to renew the cathodic protection without having to re-abrasive blast beforehand. New galvanising can also be coated but it will require the surface to be prepared in line with our recommended specification.
Existing coatings of Zinga can be directly covered with a new layer regardless of the age. The old layer will re-liquidise and fuse together to form one single homogenous Zinga layer (See How Zinga Works…)
Zinga is an excellent primer when a topcoat is required. This duplex system will increase the lifetime of the coating by up to 50%. Basically the topcoat has to break down before the zinc in Zinga even starts to be weathered. Zinga UK’s technical department can advise on the creation of any Duplex system.
Zinga’s unique organic binder enables a good resistance to mechanical abrasion as the zinc dust is protected.
The diminutive particles within the Zinga enable very good wetting characteristics and enhanced mechanical adhesion to the blasted surface. Even when it has been mechanically damaged, Zinga does not peel off or flake. Please see the BS 3900 report for impact tests.
Zinga coated steel can be de-formed or bent without fear of de-lamination. This also allows the Zinga to expand and contract with the temperature fluctuations of the substrate. Please see the BS 3900 report for evidence of this.
Zinga can be applied in temperatures ranging from +40oC to -15oC but obviously at lower temperatures the drying time is significantly extended. Please see the Zinga Application Data Sheet for guidance on this issue.
Steel that is coated with Zinga up to a d.f.t. of 60 microns can be welded to X-ray quality without the risk of porosity in the joints. Different forms of welding have different degrees of success but Arc welding with a “bead pull” technique has seen good results. The matt finish of the Zinga should be removed first using a wire brush to prevent interference with the electrical path.
Zinga is certified to BS 476 part 6 &7 classifying it as completely non-flammable. Additional to this, when exposed to extreme heat Zinga produces very low levels of smoke with corresponding low levels of toxicity. It is because of this that the MoD in the UK have approved Zinga for use in Submarines. Please see the ZingaMetall reports page for further information.
The unique organic binder used in Zinga enables it to have an unlimitedshelf-life. Additionally Zinga has an unlimited pot-life which means that unfinished pots can be re-sealed and stored for use at a later date.
