SILCOLAPSE 5020 can be used as delivered, or pre-diluted in water or in the foaming medium. In this case, the water is added to the antifoam slowly with slight stirring (do not use high shear mixers).
It is recommended not to dilute it less than 1% active material content. Check the dilution stability.
The dilution thus obtained can be stored for 24 hours.
SILCOLAPSE 5020 is normally used at concentrations comprised between 10 and 500 mg per kg of the medium to be defoamed.
The amount of SILCOLAPSE 5020 required for a particular foam problem depends on several factors, which are:
- Surfactant type
- Surfactant concentration
- pH
- Temperature
- Degree of agitation/aeration.
Each foam problem tends to be unique, sometimes to a particular process or product and even to a specific plant.
Small surfactant molecules are more readily displaced from bubble lamella than from large protein or synthetic polymer molecules, hence the latter often require higher concentrations of antifoam to achieve good foam control.
Methods of addition:
It is better to add SILCOLAPSE 5020 to the medium before than foam appears, but it can also be added later to eliminate and control foam. Continuous addition is made using a metering pump or by gravity.

SILCOLAPSE 5020 may be stored at temperatures between 2°C / 36°F and 30°C / 86°F for up to 15 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


SILCOLAPSE 5020 is a non-ionic aqueous emulsion containing dimethylpolysiloxane, and is highly effective for prevention, control and elimination of foam in aqueous media.
SILCOLAPSE 5020 contains 20% of active ingredient and is designed for industrial uses.
Other specialized defoaming agents exist for use in food contact please consult us about them.
