Vertrel SDG

Introduction to Vertrel SDG

Vertrel SDG is an engineered mixture of nonflammable hydrofluorocarbons (HFCs) and trans-1,2-dichloroethylene (t-DCE). 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-141b, HFEs, PFCs, CFCs, and aqueous cleaners when safety and environmental concerns and/or floor space and cleanliness are at a premium.

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 Vertrel SDG make it an ideal ultrasonic vapor degreasing solvent.

Features and Benefits

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 no modification
• No surfactants needed: Residue free cleaning is promoted.

Typical Applications

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

Specification Conformity Tests

Vertrel SDG has been tested in a variety of industry tests, including:
Boeing D6-17487 Revision P Solvent Cleaners; General Cleaning
ARP 1755 B Effect of Cleaning Agent on Aircraft Engine Materials

Douglas Aircraft Company Type 1: Materials and Procedures for General Exterior Cleaning of Painted and Unpainted Surfaces. (General Purpose Cleaner)

Environmental

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.

Safety/Flammability/Storage

Data from acute toxicity studies has demonstrated that 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 and toxicity-related data.

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. Addition of alcohols such as methanol, ethanol or isopropanol to Vertrel SDG will increase the flammability of Vertrel SDG. Therefore, it is recommended that alcohol should not be mixed with SDG.

Material Compatibility

SDG is compatible with metals. Plastics that may show signs of softening, swelling or other changes include acrylics, ABS and polycarbonate. Elastomers, if affected, will generally revert to within a few percent of original size after air-drying. Prior-to-use, testing of plastics and elastomers should be performed under conditions expected during normal operation (e.g., time in contact with Vertrel SDG, temperature, etc.). For more information on material compatibility, contact Miller-Stephenson.

Contact with highly basic materials, pH 10 and above, is not recommended.
