What is Halar® Coating?
Halar® is the brand name for ECTFE or Ethylene-chlorotrifluoroethylene, a partially fluorinated semi-crystalline polymer developed for chemical resistance and introduced in 1970.
ECTFE is sold under various brand names, Halar® being the most popular; it is a melt-processable fluoropolymer with properties that make it a good choice for industrial coatings.
Halar® can be applied in a much thicker coating than PTFE. Typical coatings range from 5 to 60 mils (0.005” to 0.06”) in thickness, making them several times thicker than a PTFE coating. However, the thickness of a Halar® coating is limited by the thermal mass of the object being coated.
Halar® is widely used in the oil and gas, chemical processing and pharmaceutical industries.
Key features are:
- Chemical resistance
- Low dielectric constant
- High electrical resistivity
- Cryogenic properties
- Low friction
- Hydrophobic
- High purity
Typical applications include:
- Valve seats
- Wire and Cable
- Cams
- Bearings
- Chemical storage tanks
- Centrifuges
- Pipework
- Semicon wet equipment
- Exhaust hoods
- Impellers
Fluorocarbon can provide F-LON® 7000 as a standard coating and F-LON 7070® as an FDA compliant coating.
