Pfs-2 solvent

PFS-2 Solvent is a low molecular weight perfluoropolyether which can be used in many in 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 lower boiling point and hence a higher evaporation rate compared to PFS-1. Parts cleaned with PFS-2 will dry faster than 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.

· Aerospace

These fluids provide effective heat transfer both in direct and indirect cooling applications.  Direct immersion cooling provides for more effective heat removal and therefore helps to keep the component's temperatures constant.  As a result, the failure rate is lower and the package size can be minimized.

The relative low viscosity of the Galden fluids and their wide operating temperature range permit them to act as heat transfer liquids in extreme conditions.

Galden HT is a line of 11 different dielectric fluids with boiling points ranging from 70-270ºC.  Galden HT fluids were developed to meet the increasingly demanding and diversified needs of the following industries;
