Direct coatability

Direct coating

Optimized steel for direct coating. The right coating often gives steel surfaces that extra something. That is why voestalpine developed a special additional coating that can be applied without having to prepare the steel surface.

clearcover® is the environmentally compatible passivation

clearcover® is an environmentally friendly and sustainable passivation system without chromium III or chromium VI and is free from heavy metals such as molybdenum, manganese or cobalt. The additional innovative treatment is applied to hot-dip galvanized (Z, ZM, ZF) or electrogalvanized steel strip and can be supplied in combination with oil or phosphating.

  • High level of environmental compatibility and sustainability 
  • Versatile and multifunctional in its application
  • Transparent
  • Free from CrVI and CrIII
  • Free from heavy metals
  • Very good corrosion protection (transport and storage)
  • Direct paintability without pre-cleaning and pre-treatment
  • Good joinability Spot weldability, adhesive bonding and foam adhesion
  • Resistance to chemicals and solvents (detailed information upon request)

multiface® is the all-rounder

The multiface® coating is 1 to 2 µm thick and is a multifunctional, almost invisible sealant (thin organic coating = TOC) on hot-dip galvanized steel strip (Z, ZM) with excellent corrosion protection properties and direct powder coating capabilities.

  • High level of environmental compatibility and sustainability
  • Free from CrVI and CrIII
  • Free from heavy metals
  • Reduced down to three process steps
  • Alkaline resistance during processing and application
  • Excellent anti-fingerprint properties
  • Direct powder coating possible
  • Excellent atmospheric corrosion protection (corrosion protection classes C1 and C2, DIN EN ISO 12944-2)
  •  Dry formability
  • Joinability (spot welding and adhesive suitability, foam adhesion)

Direct cost savings through reduced number of process steps (oiling, degreasing, rinsing + drying)

When using steel strip coated with multiface®, the oiled part must not be degreased, rinsed or dried. The direct formability and excellent adhesive properties of the material make it possible to directly powder-coat or adhesive-bond the material after deep-drawing. This substantially reduces the processing costs.
