Abstract

In cooperation between Dacral, Leist and Kamax the Cr(VI)-free coating system „Geomet 321 + Plus VL“ was developed on the basis of the zinc flake coating „Geomet“. The optimized topcoat „Plus VL“ guarantees a constant tightening behaviour in first and multiple tightening against different bearing surfaces. In this article, investigation results and experiences with this optimized coating system are described.
