SILFOAM® SRE
SILFOAM® SRE, which contains 20% active ingredient and 33% solids, is a versatile antifoam that is comparatively rich in emulsifier but is nonetheless easily metered because it has a relatively low viscosity.
Since SILFOAM® SRE also possesses high resistance to alkalis and acids, it may further be used in a wide range of applications in which pH is critical.

Data sheets
SILFOAM® SRE has proved ideal for tackling foam in textile auxiliaries and processes, for incorporation into cooling lubricants based on mineral oils, for separation of monomers from dispersions and conversion of dispersion into derivatives.
SILFOAM® SRE is a useful auxiliary for combating foam generated in surfactant containing formulations employed in the most diverse areas, such as the agrochemicals (plant protection agents), cleaners and petrochemicals industries.
SILFOAM® SRE is also an efficient defoamer for treating waste water.
Processing
SILFOAM® SRE is a low-viscosity emulsion, it can be metered readily, with stable dispersions easily attainable in high-viscosity formulations. In low viscosity products, preliminary compatibility and stability tests should be performed on the system to be defoamed. The amount to add to liquid formulations depends on the desired degree of foam control, but usually lies between 0.1 and 2 %.
If SILFOAM® SRE is to be added during a process, we recommend prediluting it with cold water in a ratio of 1:1 to 1:10. These diluted emulsions have a lower storage stability and should be processed as close in time as possible. If feed pumps are used, they should be of the low shear force type.
Storage
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
