ETFE Coatings

what is etfe coating?

EthyleneTriFluoroEthylene has very similar chemical resistant properties to ECTFE though is thinner and not quite so robust. Commonly used for external environmental corrosion resistant applications, there are some specific instances where ETFE outperforms other fluoropolymers.

Tefzel® is a brand name of Chemours (formerly DuPont) for their ETFE coating.

Aalberts uses the Tefzel® brand.
