HALAR® ECTFE Coating

HALAR® ECTFE is a melt processable fluoropolymer.  It possesses a unique combination of properties as a result of its chemical structure – 1:1 alternating copolymer of ethylene and chlorotrifluoroethylene.  HALAR® offers excellent chemical resistance, good electrical properties, and a broad use temperature range, from cryogenic to 300°F.  It is a tough material with excellent impact strength over its broad use temperature range. HALAR® ECTFE is one of the best fluoropolymers for abrasion resistance.

PROPERTIES OF HALAR®

Chemical Resistance - HALAR® fluoropolymer is resistant to a wide variety of corrosive chemicals and organic solvents, including strong acids, chlorine and aqueous caustic.  No known solvent dissolve or stress cracks the polymer at temperatures up to 250°F.

Electrical Resistance - The dielectric constant of HALAR® is low and stable across a broad temperature and frequency range.  The dielectric strength is 2000 volts/mil in 1 mil thickness.

Toughness and Strength - HALAR® possesses excellent mechanical properties over a wide range of temperatures from cryogenic to 300°F.  It has nylon like durability and provides excellent impact resistance at ambient and sub-ambient temperatures.

Barrier Properties - Barrier properties of HALAR® fluoropolymer are excellent, 10 – 100 times better than those of PTFE or FEP to oxygen, carbon dioxide, chlorine gas or hydrochloric acid.

HALAR® ECTFE is one of the most foremost resins for powder coating. The process allows an inert, impervious layer to be built up successively on a metal substrate to thicknesses of up to 40 mils, thereby eliminating exposure of the metal to harsh and corrosive materials.

Powder coating with HALAR® safeguards new equipment and makes possible reclamation of old equipment such as Valves, Pumps, Tanks, Centrifuges, Heater coils, Agitators and Plating racks.
