Zinc coating: process and advantages

Electrolytic galvanising with ensuing application of the passivation is the most commonly used and most cost-efficient procedure to gain a reliable corrossion protection for a range of indications.

Zinc layers with ensuing thin film passivation (DÜSP) or thick layer passivation (DISP) and, if necessary, sealing (TOPCOATS) are processed with latest state-of-the-art devices for rack and barrel plated goods in HOLDER Oberflächentechnik.

The fully automated systems ensure a absolutely constant and exactly repeatable galvanising quality – economically and for a careful conservation of natural resources.

Galvanische Verfahren – Zink. Die galvanische Verzinkung mit anschließend aufgebrachter Passivierung ist das meist angewandte und kostengünstigste Verfahren in der Metallveredelung.

Product Novatec 100 ff

Produkt Novatec 100 ff

With the brand Novatec 100 ff you get a zero-chromeium (VI) passivation in a quality that meets or even overachieves all requirements in automotive and surface finish standards.

This corrosion protection system, developed by HOLDER, is temperature-resistant and in surroundings with high thermal loads, e.g. in the engine compartment or brake systems, the protective effect remains completely unaffected.

This corrosion protection system is eco-friendly and well approved. Novatec 100 ff meets die EU-Directives (free of CrVl) and RoHS.
