SILFOAM® SE 33 is a 20% active, medium viscosity silicone defoamer emulsion that is designed for controlling foam in aqueous systems.


SILFOAM® SE 33  is safe to be used in alkaline and high temperature applications. It provides excellent foam knockdown as well as prevents foam reoccurrence longer than most conventional defoamers.


SILFOAM® SE 33  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® SE 33 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 applications.

SILFOAM® SE 33  is a versatile defoamer that is suitable to be used for many food or industrial applications, especially for food washing and processing, beverage and alcohol distillation processes.


SILFOAM® SE 33  is easily dispersible in water. It can be applied straight to an aqueous foaming system or prediluted in water before the application.


Prior to use, SILFOAM® SE 33  should be gently stirred with minimum shear to assure uniformity of the emulsion.


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.
