Corrosion protection

Zinc powder coatings are high-quality corrosion protection primers

Zinc powder coatings are high-quality corrosion protection primers with excellent protection characteristics due to electrolytic corrosion protection (an electrochemical process that can be compared to corrosion protection through external voltage). Scratches, stone schips, and similar defects are protected in a "self-healing" manner, thereby preventing the formation of underlying rust.

High-quality zinc powder coatings achieve a similar protection as hot-galvanisation. They are used for components that cannot be galvanised for technical reasons. Due to theri low level of solvents, they have a positive eco-balance.

Typical areas of application:

  • Vehicle attachments (steering wheels, leaf and parabolic springs, brake disks and drums, exhaust systems)
  • General steel construction
  • Plant construction
  • Components under thermal stress

For a variety of applications, we offer:

  • 1-component epoxy ester
  • 1-component PU (moisture-curing)
  • 2-component PU
  • 1-component system (heat-resistant)

The water-dilutable alternative is available as a single-layer system or as a primer for high-quality layer compositions with excellent corrosion protection (dry layer of 50-60 µm, 500 h salt spray test).
