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 frictionHydrophobicHigh purity

Typical applications include:

Valve seats
Wire and Cable
Cams
Bearings
Chemical storage tanks
Centrifuges
Pipework
Semicon wet equipment
Exhaust hoods
Impellers

Fluorocarbon Surface Technologies can provide F-LON® 7000 as a standard coating and F-LON 7070® as an FDA compliant coating.
