Halar coatings from AFT Fluorotec applied to pipework and vessels can provide outstanding chemical resistance, abrasion resistance and show excellent impact strength. The smooth surface of the ECTFE coatings or Halar coatings provide a surface that is less prone to pinholes, and also minimises the build up of media on the surface of the coatings.
Halar coatings are resistant to acids, bases and solvents, and provide excellent protection against chemical attack. Halar coatings also provide very high thermal insulation due to the fluoropolymer base.
Key features of Halar or ECTFE when used as a coating include:
- Excellent chemical and thermal resistance
- Excellent resistance to permeation
- Electrical insulator when the anti-static version is applied
- Flame resistance
- Smooth surface which gives excellent resistance to permeation
Halar coatings and ECTFE coatings have been used successfully in the chemical process industry for over 30 years and have a proven track record. Halar coatings have been used in the following applications (source Solvay).
- Halar or ECTFE lined chimney stack, in a power station, exposed to Sulphuric acid at 110 degrees C
- Halar coatings on a chlorine scrubber installed in a petrochem plant for 14 years, exposed to chlorinated hydrocarbons, hydrochloric acid and molecular chlorine
- Halar coatings in a process vessel for 23 years in a vinyl chloride monomer plant
Halar is a trademark of Solvay, technical name is ECTFE or a copolymer of Ethylene and chlorotrifluorethylene, a semi crystalline melt processable fluorinated polymer, with many different grades available from AFT Fluorotec Coatings
