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 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.
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.
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.
