BIO-SIL AFD/500 is a 5% active organic oil based antifoam emulsion, specifically formulated for antifoaming and de-foaming a wide range of aqueous system. Upon addition, BIO-SIL AFD/500 will rapidly knock down any foam present and will limit the generation of further foam. BIO-SIL AFD/500 is effective at low concentrations and has the added benefit of being completely silicone free.
Common Areas of Use.
Waste Water Treatment
Water Based Systems
As a processing aid: For maximum performance, BIO-SIL AFD/500 can be administered directly into the foaming system with a metered pump and is efficiently dispersed with minimum agitation. Alternatively, for maximum de-foaming efficiency, pre-dilute BIO-SIL AFD/500 with 3 to 5 parts of water momentarily before adding to the foaming system. For effective dilution, do not add the BIO-SIL AFD/500 to the water but rather vice versa.
For end use: BIO-SIL AFD/500 emulsions can be added directly from the original shipped container to the foaming system. Concentrations in the range of 0.05 to 0.1% have been determined as a good starting amount for most applications.
Testing before formulating should be carried out as systems vary.
Material Safety Data Sheets are available upon request.
The shelf life period without testing is 12 months from date of manufacture, if stored in the original unopened container at 4°C to 27°C.
Mild agitation should be carried out if stored as the nature of any emulsion is to separate without agitation over extended periods of storage.
