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.

SILFOAM® SD 170 A is recommended for all organic systems that require a compatible antifoam agent. It is particularly recommended for systems with high surfactant content or which entail high shear forces. In those systems purely organic defoamers rapidly become ineffective. SILFOAM® SD 170 A also serves as an antifoam agent for strongly foaming, fine particle rich suspensions and in the production of redispersible powders.


SILFOAM® SD 170 A is an excellent additive to detergents and organic fabric softener base emulsions to aid in controlling foam in the wash and rinse cycles.


SILFOAM® SD 170 A can be used undiluted.

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.
