DuPont™ Vertrel® SDG Specialty Fluid

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.

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 has "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.

All components are listed in the TSCA inventory. Refer to the MSDS for regulatory information.

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.

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.

Flammable Properties

User should clear equipment of all vapors and liquids before performing any maintenance operations that could result in an ignition source.  Users also need to consider the possibility of vapor flammability of this product to determine guidelines for its safe handling in all other parts of the user's operations.  For example, when opening a partially-filled container that has been stored, treat the gas/air mixture as if it is flammable.

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.
