Halar® is recommended for high purity fluid systems in semiconductor, pharmaceutical and biotech industries
Halar®(ECTFE) Coating Technology The Facts
What It Is
Halar® also known as ECTFE
Halar® coating has two main properties chemical resistance and corrosion resistance.
- Chemical and thermal resistance
- Optimum permeation resistance
- Flame resistance
- Hard finish resistant to abrasion
Halar® is a melt processable polymer specifically designed for application using an electrostatic powder gun. All parts are cleaned and pre-treated before Halar® is applied using a sandblasting process. This procedure cleans and etches the surface making it ideal for Halar® to bond and seal. Halar® is applied in stages to build up the coat thickness. Halar® is melted and applied at 260°c.
Halar® Coating Properties
Halar® shows excellent chemical resistance and exceptional barrier properties over a wide range of temperatures. Nowadays Halar® is unanimously accepted and acknowledged as top-performance coating for universal corrosion control (pH 1-14). Halar® is hydrophobic and virtually unaffected by most harsh chemicals commonly encountered in industry today. Among those substances that Halar® is resistant to are strong mineral and oxidizing acids, alkalis, metal etchants, liquid oxygen and most organic solvents. Furthermore, it exhibits outstanding exterior durability (stability to UV light and weather) and resistance to high energy radiation.
Typical Halar® applications include vessels, reactors, piping systems, pumps, valves, centrifuges, agitators, impellers, hoods, filters, sieve plates, caustic collectors, electroplating equipment’s, storage tanks and ductworks.
Halar® is also recommended for high purity fluid systems in semiconductor, pharmaceutical and biotech industries, particularly where the process surface must be smooth, chemically inert and resistant to bio fouling.
