Halar® ECTFE, a copolymer of ethylene and chlorotrifluoroethylene, is a semi-crystalline melt processable partially fluorinated polymer. It is availible in different grades that are specifically designed for electrostatic powder coating.
Halar® ECTFE is particularly suitable for use as a coating material in protection and anti-corrosion applications thanks to its unique combination of properties.
- Very good chemical and thermal resistance
- Optimum permeation resistance
- Outstanding flame resistance
- Very good surface characteristics
- Surface smoothness
Typical applications served by Halar® ECTFE include those in contact with highly corrosive or ultrapure chemicals such as strong inorganic bases and strong mineral and oxidizing acids including:
- Semiconductor chemical storage tanks and ductwork
- Piping systems
- Exhaust hoods
- Electroplating equipment
Halar® ECTFE is available in different grades that are specifically designed for electrostatic powder coating, fluidized bed coating, or both.
Electrostatic Powder Coating
Generally the procedure involves substrate preparation, spray coating, baking and cooling. Several passes maybe required to obtain the desired Halar® ECTFE load and build up coating thickness.
