Product Benefits
  • 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.

Instructions for Use

Silcolapse® 482 is efficient both in aqueous and in anhydrous media. It disperses readily provided a suitable thinner is used. It 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. It 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 water dispersible such as : Certain ketones : methylethylketone or methylisobutylketone, Certain alcohols: tertiary butanol, dodecanol-1 or ethyl2hexanol, Certain ethers: ethyl ether or isopropyl ether.
