Coil Coating

An example of the high efficiency of Openair-Plasma^® activation is the manufacture of pre-coated sheet metal (coil coating). This material is needed in the industrial production of household appliances and in the automotive industry.

In the coil coating process, strip metal is provided with a surface coating or varnishing to achieve optimum protection against corrosion and to simplify subsequent production processes. For long-term layer and varnish adhesion, the aluminum strip must first be completely cleaned of rolling oils in an ultrafine cleaning process.
