Alkaline zinc
Alkaline zinc is a coating with broad horizons. It is an electrolytic, inorganic, corrosion-protecting coating suitable for most steel products used in semi-corrosive environments/applications. With this type of galvanising you save costs and also get a foundation suitable for varnishing.
Why Alkaline zinc?
The thickness of the zinc layer can be adapted to customer requirements, but has good corrosion-protecting qualities even with thin layers. Most common is 8–12 μm.
Adding a sealer/topcoate will increase corrosion protection and give controlled friction when needed.
As this coating extends the lifespan of your product, it contributes to a more sustainable life cycle.
It has good metal distribution over the current density areas, which gives even layers.
The application temperature range is <+150°C.
