SILFOAM® SC 201 is a 100% active, low viscosity, silicone defoamer compound based on Wacker's innovative polysiloxane and silica technology. It is highly efficient to control foam longer than most conventional defoamers in high alkaline and high temperature applications.


SILFOAM® SC 201  can be used directly to control foam in oil or solvent based foaming systems. It can also be easily emulsified into an emulsion for defoaming in aqueous based foaming systems.


SILFOAM® SC 201  is certified as Kosher. It is suitable for use in indirect food contact and secondary direct food additive applications listed under FDA 21 CFR176.170; 176.180; 176.200; 176.210;175.300; 177.2600; 178.3400; and 173.340. Some of the listed applications have regulatory limitations, please contact your Wacker Sales Representative for further information.


SILFOAM® SC 201  is also registered by NSF to Category Code 3D (as a fruit and vegetable washing product) and Q5 (for use as a foam control agent in egg washing machines). Please refer to the NSF sections for further guidelines on these application.

SILFOAM® SC 201  can be used in various Food, Industrial, and Consumer applications. Some of the applications have regulatory limitations, please contact your Wacker Sales Representative for further information. 


SILFOAM® SC 201 is most efficient if introduced into the system before foaming has begun. 


SILFOAM® SC 201 may be introduced as is, or by dispersing in one or more of the ingredients of the system in which foam is to be controlled. It also can be pre-dispersed in an appropriate solvent and then add this dispersion to the foaming system. The solvent used for dilution could be:


  • Aromatic hydrocarbons – toluene
  • Aliphatic hydrocarbons – mineral spirits, t-butanol
  • Esters


Note: If solvents are used to aid dispersing the SILFOAM® SC 201, the FDA and contact sanctioning becomes null and void.


Prior to use, it is recommended that SILFOAM® SC 201 be stirred under low shear for a few minutes before using. This will ensure that the fillers are completely dispersed in the material.


The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
