Halar ECTFE is a partially fluorinated semi-crystalline polymer offering a unique combination of mechanical properties, permeation resistance, thermal and chemical resistance, and versatility.
Halar ECTFE is a melt processable fluoropolymer manufactured by Solvay Solexis. Its unique combination of properties is credited to its chemical structure, a 1:1 alternating copolymer of ethylene and chlorotrifluoroethylene. Halar coatings provide outstanding chemical resistance. It is resistant to strong mineral and oxidizing acids, alkalis, metal etchants, liquid oxygen, and essentially all organic solvents except hot amines. Halar coatings provide good electrical properties, a broad use temperature range from cryogenic to 300°F (150°C), and meets the requirements of UL-94V-O vertical flame test in thicknesses as low as 7 mils (0.18mm). It is a tough material with excellent impact strength.
These characteristics have made Halar the material of choice for many applications across multiple industries. It has been widely utilized in the chemical, pharmaceutical, and microelectronics industries for chemical resistance. Since 1990 Halar powder coatings have been successfully used for corrosion protection of exhaust duct systems that must meet the FM 4922 fire safety standard. Halar coatings have also been used to replace PVDF sheet linings in ultrapure water (UPW) systems.
As you can see, Halar is a versatile material with almost limitless applications.
Chemical processing equipment such as filter tanks, small vessels, valves, reactors and flanges piping have been successfully coated. These savage corrosive and high temperature environments are combated with a multi-coat application of one of many fluoropolymers such as PTFE, Kynar, HalarŠ, ECTFE and ETFE. We focus on the preparation of the metal substrate prior to the application of the chemical resistant coating, as it is the foundation of the coating adhesion necessary in these high stress environments.
