SILFOAM® SD 170 A is an anhydrous antifoam agent based on organofunctional silicone fluid compounds which exhibit a high compatibility with organic systems. SILFOAM® SD 170 A has significant foam knock down and excellent sustaining antifoam power.

The exact dosage must be determined in preliminary tests. We recommend starting with amounts between 0.05 and 0.3%. Generally, the product should be added as it is, as its self-dispersing properties will usually ensure an adequate and homogeneous distribution. If the SILFOAM® SD 170 A is diluted with water, the resultant dispersion must be used quickly. It is recommended that SILFOAM® SD 170 A be stirred before use.


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.
