SILCOLAPSE 482 is efficient both in aqueous and in anhydrous media. It disperses readily provided a suitable thinner is used.

SILCOLAPSE 482 is normally used at concentrations of between 1 and 100 mg/kg of system to be defoamed.

SILCOLAPSE 482 is ready to use as delivered, or it can be pre-diluted to around 1% to 10% active matter by slowly adding, 99 or 90 parts of selected thinner.

SILCOLAPSE 482 can be diluted in solvent of silicone oil.

  • In anhydrous media: aliphatic, aromatic hydrocarbons, chlorinated hydrocarbons.
  • In aqueous media: in this case thinner should be either watersoluble or waterdispersible such as :
  • Certain ketones : methylethylketone or methylisobutylketone.
  • Certain alcohols: tertiary butanol , dodecanol-1 or ethyl2hexanol…
  • Certain ethers: ethyl ether or isopropylether.
SILCOLAPSE 482 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 482 is a defoamer compound containing polydimethylsiloxane oil and silica.



  • Good efficiency at high temperature.
  • Easy to use: it can be used as delivered, or emulsified with usual surfactants of silicone antifoam emulsions.
  • High efficiency at alkaline pH.
  • Low dose efficiency, at around 1 to 100 mg per kg of system to be defoamed.
  • Chemically inert with regards to the substance to be defoamed therefore leaving its properties unchanged.


SILCOLAPSE 482 is multi-purpose :

  • Crop protection products: product formulation (emulsifiable concentrates and aqueous dispersions). It is exempted from tolerance under chapter 40 CFR 180.910 for crop protection and 40 CFR 180.930 for animal food.
  • Detergency: liquids and powdered detergent, surfactants.
  • Pulp Industry: Kraft or Sulfite process.
  • Chemicals: distillation, extraction, filtration …
