Dörken: PFAS-free zinc flake system receives approval
A PFAS-free zinc flake system from Dörken was closely scrutinized and tested against specific requirements. With success, a Dörken topcoat has now 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 working intensively on this issue and already has a number of PFAS-free products - both basecoats and topcoats - in its portfolio. The zinc flake coating is particularly concerned with replacing fluoropolymers (such as PTFE), which are 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 the first ever global approval of a PFAS-free system in the automotive industry.
PFAS-free alternative system from Dörken
The topcoat is responsible for multifunctional properties in combination with a zinc flake basecoat or other metallic substrates. It refines the zinc flake basecoat into a layer system and ensures a very narrow friction coefficient window. In addition, the coating is not only free from PFAS, but also from 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.
