Highly corrosion resistant

Zinc-nickel

Zinc-nickel coating: process and advantages

The electro plated zinc-nickel alloy (12 to 15% nickel) is particularly successful in areas with the requirement of extremely high corrosion protection under high temperature loads.

Classic applications of parts with zinc-nickel-coatings are the engine compartment, chassis and the underbody area in automotive as well as offshore applications.

Parts subject to high temperature loads resist against starting base material corrosion in the salt spray test according to DIN EN ISO 9227 for more than 1000 hours.

The post treatment with selected topcoats enables to substantially increase the corrosion resistance and the resistance against chemical substances.

Product Novatec 300 ff

Under the name Novatec 300 ff you receive a chrome(VI)-free galvanic zinc surface 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. The protective effect remains completely unaffected in surroundings with high thermal loads, e.g. in the engine compartment or in the brake systems.

The corrosion protection system is environmentally friendly. Novatec 300 ff complies with the EU directives CrVI-free and RoHS.
