Halar®(ECTFE) Coating

Halar® ECTFE, a copolymer of ethylene and chlorotrifluoroethylene, is a semi-crystalline melt process able partially fluorinated polymer. It is available in different grades that are specifically designed for electrostatic powder coating. Halar provides excellent chemical resistance and electrical insulating properties combined with a broad-use temperature range from cryogenic to 150ºC. It is a tough material with excellent impact strength over its broad use-temperature range. Halar is one of the best fluoropolymers for both abrasion and permeation resistance because of its tight internal structure. We are leading Manufacturer of Halar Coating in Mumbai

Thickness

0.5-1mm(500- 1000 microns)

Significance

Halar exhibits outstanding chemical resistance and excellent barrier properties. Halar is virtually unaffected by most corrosive chemicals commonly encountered in industry. Among those substances that Halar fluoropolymer is resistant to are strong mineral and oxidizing acids, alkalis, metal etchants, liquid oxygen and most organic solvents except hot amines (e.g. aniline, dimethylamine). Typical of fluoropolymers, Halar is attacked by metallic sodium and potassium. Halar however is very resistant to sodium or potassium hydroxides, depending on exposure time and temperature.

Applications

  • Chlorine and chlorine dioxide scrubbers using strong sodium hydroxide solution
  • Metal pickling and plating tanks using chromic acid mixtures
  • Semiconductor work benches exposed to sulfuric acid - hydrogen peroxide mixtures
  • The storage of concentrated acids
  • The manufacture of sodium chlorate

HALAR coatings are opted for many chemical process equipments such as:

  • Agitators
  • Centrifuges
  • Containers
  • Hoods
  • Piping Systems
  • Caustic Collectors
  • Semiconductor Chemical Storage Tanks
  • Electroplating Equipment
