Intech Services, the sole distributor of DuPont™ Teflon® industrial coatings, offers Tefzel®, previously referred to as ETFE (ethylene tetrafluoroethylene) Teflon®. DuPont has expanded the product line with a powder primer (532-6405) and a new high-build clear topcoat (532-6410). The topcoat can be applied to film builds of 80 to 100 mils, depending on part geometry.
The thermoplastic coating provides chemical resistance and high operating temperatures, a high melting point for thermal stability, and reduced low-temperature embrittlement. It is tough and electrically insulative, with superior substrate adhesion, the manufacturer states.
