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.

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.
