Vertrel™ SFR
Specialty Fluid

Lead Free and No Clean Flux RemovalTechnical Information
Introduction• Low toxicity

Vertrel™ SFR is an engineered mixture of nonflammable• Zero ozone depletion potential (ODP)

hydrofluorocarbons (HFCs), trans-1,2-dichloroethylene(t-DCE) and methanol.
Vertrel™ SFR is designed to remove difficult to remove hightemperature fluxes used in lead free and no clean solders.
It has excellent solvency power for a wide range of soils,
including ionic soils. The low surface tension and nonflammable properties of Vertrel™ SFR make it an ideal
ultrasonic vapor degreasing solvent.
Vertrel™ SFR is a non-ozone depleter and can replace manysolvents, such as trichloroethylene (TCE), n-propyl bromide(nPB), HCFC-225 blends, HCFC-141b, HFEs, PFCs, andCFCs. Vertrel™ SFR can also replace aqueous cleaners• Low global warming potential (GWP)• Existing equipment can be used with minor or nomodification• No surfactants needed: Residue free cleaning is promoted.

Typical Applications• Defluxing• Oil, grease, and wax removal• Precision cleaningSpecification Conformity Tests

where floor space and cleanliness are at a premium.

Vertrel™ SFR has been tested in a variety of industry

Environmental Properties
Vertrel™ SFR has zero ozone depletion potential and low
global warming potential. See Table 1 for various
environmental properties of Vertrel™ SFR. Vertrel™ SFR is
accepted by the U.S. Environmental Protection Agency (EPA)
under the Significant New Alternatives Policy (SNAP) program
as a substitute for ozone-depleting substances (solventcategory). It is not SNAP approved for aerosol packages.

Disposal and Recovery of Spent Solvent
Please read SDS and discuss disposal options with aknowledgeable Chemours or distributor representative
prior to disposal or recovery. The presence of highconcentrations of certain soils (such as petroleum-based
lubricating oils) may affect the flammability characteristicsof the material during disposal and/or recovery operations.
Users should test for flammability in their particularapplication and test the spent Vertrel™ SFR to ensure
proper classification for waste disposal.

Large amounts of water may extract the alcohol componentof Vertrel™ SFR and reduce cleaning performance. Therefore,
to reduce alcohol loss, use desiccant dryers, rather thanwater separators, in the condensate return line.
