- How to Use
Disperse the oil phase into DOWSIL™ EL-7040 Hydro Elastomer Blend using simple mixing. There is no need for post-shearing. This hydrophilic product offers enhanced compatibility with a wide range of ingredients, both polar and non-polar, along with a caprylyl methicone carrier thereby providing a novel form of delivery for other formulation components. Formulations can be made using a cold process.
Processing
DOWSIL™ EL-7040 Hydro Elastomer Blend is a viscous product that exhibits shear thinning behavior. The following information will aid in the selection of the proper equipment to use when processing DOWSIL™ EL-7040 Hydro Elastomer Blend out of a drum.Pump Recommendation
GRACO BULLDOG 10:1 Pump with follower plate. For more information, contact GRACO at www.graco.com. Note: GRACO offers various models, and other pump manufacturers may offer similar equipment equally capable of processing the material efficiently. Users should work directly with the pump manufacturer to determine the best design for their needs. Customer-specific pump design considerations:
1. Pressure and Flow Requirements
a. Air supply pressure: Will depend on plant’s air supply capabilities.
b. Discharge pressure: Will depend on total pressure required to move the silicone organic elastomer blend from point A to point B. Pressure drops due to elevation, frictional losses within the piping, fittings, valves, filters, etc., will need to be considered.
c. Flow requirements: Will depend on how quickly the user wishes to transfer the silicone organic elastomer blend from a 208 liter (55 gallon) drum into a vessel.2. Material Viscosity in cP (mPa•s) at the Application Temperature
DOWSIL™ EL-7040 Hydro Elastomer Blend is shear thinning. It is the responsibility of the user to determine the effective viscosity based on the user’s application. Once the material is pushed through the pump by the follower plate and processed in the pump, the product will shear thin and process as a lower viscosity fluid.3. Construction Material for Wetted Parts
Stainless steel is recommended but carbon steel may also be used.4. Construction Material for Seals and Gaskets
VITON or TEFLON materials are recommended. Please contact Dow for alternatives.Clean-up
Non-polar organic or silicone solvents are recommended for soaking or cleaning equipment.- Formulation Tips
- DOWSIL™ EL-7040 Hydro Elastomer Blend may be formulated into oil-in-water emulsions, water-in-silicone emulsions, water-in-oil emulsions and anhydrous products.
- It may be added to the oil phase or silicone phase in an emulsion formulation. In some cases, it may be possible to add DOWSIL™ EL-7040 Hydro Elastomer Blend to the water phase provided sufficient levels of elastomer and shear are applied to cause a phase inversion.
- It may be possible to post-add to emulsions provided the emulsion is viscous enough for the elastomer blend to be dispersed.
- For ease of use, its viscosity may be reduced by blending with a compatible solvent.
- DOWSIL™ EL-7040 Hydro Elastomer Blend may structure over time becoming crumbly in appearance, especially at the surface. This is a reversible phenomenon. The elastomer blend will return to a creamy paste-like texture via mixing or pumping.
- It is dispersible in a variety of liquid oils.
- It may be formulated with organic oils and silicon-based materials with the use of mixers and may be subjected to high shear devices such as homogenizers and sonolators.
- DOWSIL™ EL-7040 Hydro Elastomer Blend may be subjected to up to 80°C for up to 3 hours. When heat is used, the material should be processed in an enclosed vessel to prevent the caprylyl methicone from volatilizing; the vessel should be inerted at temperatures over 40°C (104°F).
