Perfluorosolv PFS-2 Solvent
PERFLUOROSOLVTM PFS-2 Solvent is a low molecular weight
perfluoropolyether which can be used in many industrial applications. PFS-2
performs well in many electronic and semiconductor cleaning applications,
such as:
-
Pump and compressor cleaning
-
Vapor blanketing
-
Degreasing
-
Flash Point reduction
-
Dewatering
-
Trace residue elimination
PFS-2 solvent has been formulated to be compatible and completely miscible
with perfluoropolyether (PFPE) and perfluorocarbon fluids at all temperatures
and chlorotrifluoroethylene (CTFE) oils and greases above 45oC. All of
these materials are used extensively in semiconductor and electronic manufacturing.
PFS-2 solvent can also act as a diluent in the application of more viscous
PFPE fluids or greases.
PFS-2 solvent is non-flammable and well suited for cleaning operations
where:
-
solvents are applied to hot components
-
solvents are heated prior to application
-
solvents are pressure sprayed on components
-
solvents are used in forced air stream cleaning
-
extended immersion baths are required
PFS-2 has a lower boiling point and hence a higher evaporation rate compared
to PFS-1. Parts cleaned with PFS-2 will dry faster that those cleaned with
PFS-1. When using PFS-2, especially in open baths, it may be necessary
to take precautions to avoid excessive losses from the bath.
Typical properties of PFS-2 solvent versus PFS-1 are listed below.
