SILCOLAPSE A is as efficient in aqueous as in anhydrous systems. It can easily be dispersed in these systems as long as the appropriate diluent is used.
SILCOLAPSE A is normally used at concentrations of between 1 and 100 mg/kg of system to be defoamed. It can be used as it is, or if necessary be diluted to a concentration varying between 1 and 10% (slowly add 99 or 90 parts of the chosen diluent to between 1 and 10 parts of SILCOLAPSE A).
SILCOLAPSE A can also be emulsified with non ionic surfactants like stearates.

SILCOLAPSE A may be stored at temperatures between -5°C / 23°F and 40°C / 104°F for up to 18 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


SILCOLAPSE A is a 100% active compound based on Polydimethylsiloxane oil and silica.
This product is mainly intended for treatment of anhydrous and aqueous foaming systems and has many applications in food and industry.



  • Very high foam control capability.
  • Easy to use: it can be used as delivered or pre-diluted in a solvent or in part of the foaming system.
  • Easy to disperse in most anhydrous and aqueous foaming systems.
  • Outstanding behaviour in alkaline systems.
  • Low dose efficiency, of around 1 to 100 mg per kg of system to be defoamed.
  • Chemically inert with regards to the system to be defoamed...
