(1) As with most fluorinated liquids, Novec 7100DL fluid will absorb into fluorinated plastics (e.g. PTFE) and elastomers (e.g. FFKM, FKM types) over

longer exposures. Absorption and swelling of silicone rubber are also observed.

(2) Butyl Rubber best for extended exposure > one month.

(3) Some surface oxidation of copper during testing.
