ECTFE Coatings / Halar Coatings

ECTFE (or Halar coatings) is a melt-processable fluoropolymer with a 1:1 alternating copolymer structure of ethylene and chlorotrifluoroethylene. As part of the fluoropolymer family, ECTFE coating or Halar® 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 Kalar) is part of the fluoropolymer family offering similar properties to ECTFE.

ECTFE / Halar® 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 petrochemcial industry.
