                                                         Precision Cleaning And Degreasing

Introduction                            DuPont™ Vertrel® SDG is an engineered mixture of non-flammable hydrofluorocarbons (HFCs) and trans-1,2-dichloroethylene (t-DCE). DuPont™ Vertrel® SDG is designed to replace trichloroethylene (TCE) and n-propyl bromide (nPB); and perform in applications where maximum cleaning power is needed.  It can also be used as a substitute for other cleaners such HCFC-225 and its blends, HCFC-14 lb, HFEs, PFCs, CFCs, and aqueous cleaners when safety and environmental concerns and/or floor space and cleanliness are a premium. DuPont™ Vertrel® SDG has excellent solvency power for a wide range of soils including oils, greases, waxes and hydraulic fluids.  The high solvency power, low surface tension and non-flammability properties of DuPont™ Vertrel® SDG make it an ideal ultrasonic vapor degreasing solvent. Features and Benefits: DuPont™ Vertrel® SDG does a good job balancing performance with favorable environmental and worker safety properties.  Excellent solvency power (KB Value = 95):    Superior cleaning performance  Good solvency for silicone fluids  Fast drying:  Increases productivity  Low surface tension:  Able to penetrate and clean  tight areas  Compatible with most plastics, elastomers, and metals  Can be used with ultrasonics  Non-flammable  Low Toxicity  Zero ozone depletion potential  Low global warming potential  Existing equipment can be used with minor or non modification  No surfactants needed:  Residue free cleaning is promoted.                                Typical Applications DuPont™ Vertrel® SDG is ideal for a wide range of cleaning applications including:  Oil, grease, and wax removal  Silicone carrier fluid  Silicone grease removal  Precision cleaning Environmental DuPont™ Vertrel® SDG ha "zero" ozone depletion potential and low global warming potential.  See table below for various environmental properties of Vertrel® SDG.  Vertrel® SDG 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. Environmental                        DuPont Property                             Vertrel SDG Ozone-Depletion Potential (ODP)                              0 Global Warming Potential (GWP/100yr ITH)*             148 Volatile Organic Compounds (VOC, g/liter)               1150 *based on IPCC Second Assessment Report values All components are listed in the TSCA inventory.  Refer to the MSDS for regulatory information.                                                              Safety/Flammability/Storage                                  Data from acute toxicity studies has demonstrated that Vertrel® SDG has low toxicity.  It has a calculated AEL (Acceptable Exposure Limit) of 193 ppm based on its individual components.  AEL is an airborne inhalation exposure limit established by DuPont™ that specifies time-weighted average concentrations to which nearly all workers may be repeatedly exposed without adverse effects.  The calculated AEL is in accordance with ACGIH formulas for TLVs for mixtures.  Vertrel® SDG is a slight skin and eye irritant and has low acute inhalation toxicity. Please refer to the MSDS for information on detailed exposure limits an toxicity-related data. DuPont™ Vertrel® SDG exhibits no closed cup or open cup flash point and is not classified as a flammable liquid by NFPA or DOT.  The product is volatile, and if allowed to evaporate and mix with air, the vapor may become flammable.  Flash point data and vapor flammability limits in air are shown in the table.

DuPont™ Vertrel® SDG is thermally stable and does not oxidize or degrade during storage.  Store in a clean, dry area.  Protect from freezing temperatures.  If solvent is stored below -10ºC (14ºF), mix prior to use.  Do not allow stored product to exceed 52ºC (125ºF) to prevent leakage or potential rupture of container from pressure and expansion.
