    16.01.2026 Breakthrough: DÖRKEN achieves first approval for a PFAS-free alternative system

    A PFAS-free zinc flake system from DÖRKEN was closely examined and tested against specific requirements. With success: a DÖRKEN topcoat has been approved for the VW specification VW TL245 Ofl-t647.

    The European Commission's decision on a possible ban on PFAS compounds is still pending. Nevertheless, DÖRKEN is addressing this issue intensively and already has several PFAS-free products – both base and topcoats – in its portfolio. In the case of zinc flake coatings, the focus isparticularly on replacing fluoropolymers (such as PTFE) commonly used in the industry as lubricants. The coating company has now achieved its first breakthrough: DÖRKEN Topcoat DELTA-PROTEKT® TC 502 GZ has been approved for the VW TL245 Ofl-t647 specification. This is thefirst global approval of a PFAS-free system in the automotive industry.  

    The topcoat, in combination with a zinc flake basecoat or other metallic substrates, is responsible for multifunctional properties. It refines the zinc flake basecoat into a coating system and ensures a very narrow coefficient of friction window. In addition, the coating is not only free ofPFAS, but also of harmful heavy metals and has a silver finish.   

    The decision on the potential ban on PFAS compounds may still be pending, but the coating experts at DÖRKEN are well prepared in any case
