DuPont™ Vertrel® SFR - Specialty Fluid

Introduction

DuPont™ Vertrel SFR® is an azeotrope-like blend of non-flammable hydrofluorocarbons (HFCs), trans-1,2-dichloroethylene (t-DCE) and methanol.

DuPont™ Vertrel® SFR has excellent solvency power for a wide range of soils.  It is designed to remove high temperature fluxes used with no lead and no clean solders.  The low surface tension and non-flammability properties of DuPont™ Vertrel® SFR make it an ideal vapor degreasing solvent.

DuPont™ Vertrel® SFR is a non-ozone depleter and is intended to replace trichloroethylene (TCE), n-propyl bromide (nPB), HCFCs, HFEs, PFCs, and CFCs as well as other solvents that do not have the favorable safety, health, and environmental properties.  DuPont™ Vertrel® SFR can also replace aqueous cleaners in certain instances where floor space and cleanliness are at a premium.

Vertrel SFR is accepted by the US Environmental Protection Agency under the Significant New Alternatives Policy (SNAP) program as a substitute for ozone-depleting substances (solvent category).  It is not SNAP approved for aerosol packages.
