Description & Characteristics

Perfluoro-1,3,5-trimethylcyclohexane, C9F18 is a fully-fluorinated, odourless, colourless liquid with the following characteristics:

  • Compatibility with most construction materials
  • Excellent chemical and thermal stability
  • Non flammability
  • Practically non-toxic1

  • Applications

    Perfluoro-1,3,5-trimethylcyclohexane is predominantly used as a tracer and taggant under the trade name of Flutec TG-PTMCH.

    Safety, Handling and Storage

    Although Perfluoro-1,3,5-trimethylcyclohexane is considered biologically and chemically inert, good laboratory practice should be observed when handling. Perfluoro-1,3,5-trimethylcyclohexane has an indefinite shelf life if properly stored in its original sealed container. Safety data sheets are available on request.
