Ethylene Chlorotrifluoroethylene (ECTFE) or Halar® coating is a melt-processable fluoropolymer with a 1:1 alternating copolymer structure of ethylene and chlorotrifluoroethylene. As part of the fluoropolymer family, ECTFE coatings have a unique combination of properties including excellent chemical resistance, good electrical properties, a broad-use temperature range, outstanding abrasion resistance, and excellent impact strength.
Additionally, PVDF (also known as Kynar) is part of the fluoropolymer family offering similar properties to ECTFE.
ECTFE coatings resist a wide variety of corrosive chemicals and organic solvents, including strong acids, chlorine, and aqueous caustics making them ideal for vessels and process equipment for many industries including the petrochemical industry.
