Abstract

Since several years, new products appeared on the market replacing classic phosphate – based conversion
coatings. This presentation will focus on the replacement of tricationic zinc phosphating systems for the

In the second part of the presentation, an outlook will be given on anti-corrosion packages for the coming
decade. An example of a very lean automotive paint shop will be discussed.
