​SILCOLPASE C581 could be directly or pre-diluted before adding the system, when dilute either with cool soft or deionised water for a use within 24 hours, In this case, the water is added to the antifoam slowly with slight stirring (do not use high shear mixers).

SILCOLAPSE C 581 may be stored at temperatures between 2°C / 36°F and 30°C / 86°F for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


​SILCOLAPSE C581 is a silicone antifoam emulsion based on BSI new generations high efficient silicone compounds. It is recommended for the prevention, control or elimination of foam in  aqueous systems.



  • ​Easy dispersion in aqueous media. 
  • Homogeneous and stable under wide PH and temperature range.
  • High antifoam efficiency in many applications.
  • High defoaming performance both at room temperature, middle and high temperature

​SILCOLAPSE C581 can be used in many industries such as :

  • Waste-water treatment : neutralization and biological step, outlet.
  • Pulp industry : various processing steps (black liquid, waste water).
  • Chemicals : distillation, extraction, filtration.
  • Oil-industry : extraction, butadiene process, amine-sweetening units.
  • Textile : textile additive, washing
