The combination of layers is particularly suitable for bulk articles, such as nuts, bolts, and many types of turned and punched parts.

The thickness of the zinc layer is at least 12 µm, and the passivation meets the requirements of the automotive and electrical industries.

Besides the standard Duploseal Si, our Duploseal SiL with its integrated lubricant additives is available specially for threaded parts. It ensures that the coefficients of friction required by the end users are in very many cases achieved without additional lubrication.

Compared to many another method of corrosion protection – even from the area of flake coatings – Superzink 600 features a very high level of abrasion resistance. This ensures that the risk of damage to the coating during transportation, sorting and weighing as well as during final assembly is reduced quite considerably.

We would be pleased to apply sample coatings to your components for you.
