SILFOAM® SE 36
SILFOAM® SE 36 is an antifoam emulsion that is largely compatible with surfactants. Unlike conventional antifoam emulsions, solutions of SILFOAM® SE 36 are stable for relatively long periods.
SILFOAM® SE 36 is particularly efficient at keeping cloudiness in surfactant-containing solutions to a minimum. We recommend that preliminary trials be carried out as these systems are highly diverse.
In surfactant-rich formulations, such as liquid detergents, textile additives and cleaning agents.
As SILFOAM® SE 36 is a medium-viscosity emulsion, it can often be metered directly. To produce a stable dispersion in high-viscosity formulations, it is best to stir at low shear rates. Preliminary compatibility and stability tests should be performed on the system to be defoamed.
Addition of 1 - 2 % usually suffices for liquid detergents, with no need for predilution; from 0.2 - 1 % is recommended for cleaning agents.
If SILFOAM® SE 36 is to be added during a process, predilution with cold water in a ratio of 1 : 1 to 1 : 10 will result in more accurate metering. 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.
Minimum temperature allowed during storage and transportation: 0 °C
Maximum temperature allowed during storage and transportation: 40 °C
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.
