SILFOAM® SD 170 A
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.
