- Application Information
To incorporate DOWSIL(TM) EL 9140 DM Silicone Elastomer Blend into a formula, it should be combined with the oil or silicone phase. It is important for the elastomer blend to be uniformly dispersed in the oil/silicone phase before proceeding.
The viscosity of DOWSIL(TM) EL 9140 DM Silicone Elastomer Blend decreases as it is diluted with other oils. Figure 1 illustrates this effect when XIAMETER(TM) PMX-200 Silicone Fluid 1.5 cSt is used as the diluent.

Formulation Tips
DOWSIL(TM) EL-9140 DM Silicone 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.
- For ease of use, its viscosity may be reduced by blending with dimethicone.
- It may be incorporated in formulation with the use of mixers and may be subjected to high shear devices such as homogenizers and sonolators.
- It is dispersible in a variety of liquid oils, as referenced in the compatibility chart in Table 1.
- Because the elastomer is stable, DOWSIL(TM) EL-9140 DM Silicone Elastomer Blend may be subjected to heat for a short duration. When heat is used, the material should be processed in an enclosed vessel to prevent the dimethicone from volatilizing; the vessel should be inerted at temperatures over 60°C (140°F).
Processing
DOWSIL(TM) EL-9140 DM Silicone Elastomer Blend is a high viscosity material, but like DOWSIL(TM) 9040 Silicone Elastomer Blend, this product is strongly shear thinning and can be pumped using suitable equipment. Information regarding suitable equipment may be found in the product information sheet for DOWSIL(TM) 9040 Silicone Elastomer Blend.

At lower viscosities, dispersions often will separate over time to produce an elastomer-rich phase and a solvent-rich phase. In most cases, the elastomer-rich phase is the denser phase and appears at the bottom of the container. Mixing DOWSIL(TM) EL-9140 DM Silicone Elastomer Blend with polar solvents can lead to a collapse of the elastomer network and the elastomer may appear as a white precipitate, or flock. In the above table, a notation of “compatible” indicates a homogeneous system immediately after mixing.
