SILFOAM® SE 2262
SILFOAM® SE 2262 is a low to medium viscous, water-dispersible antifoam emulsion that is based on an organomodified polysiloxane.
SILFOAM® SE 2262 prevents foaming (act as an antifoam) and destroys existing foam (acts as defoamer) in a large number of aqueous systems. It is ideal for systems in which silicones would usually cause problems:
- PVC polymerization, degassing & stripping
- Manufacture and processing of polymer dispersions for textiles, paper, paints and surface coatings as well as adhesives
- Cooling lubricants
- Textile formulations
In general we recommend stirring the emulsion before use (approx. 3 minutes with a propeller stirrer at 200 – 400 rpm). But be cautious: too high shear can break the emulsion.
The typical dosage is in the range of 0.05 to 1.0 % and is best determined by preliminary tests.
SILFOAM® SE 2262 can be dosed undiluted, as it is already sufficiently dispersed by its emulsion form.
If the use of SILFOAM® SE 2262 should be necessary in diluted form, we recommend preparing dilutions by stirring SILFOAM® SE 2262 gently into cold water. Dilute solutions should be used up quickly as the more dilute they are, the sooner they tend to separate. A 1:1 aqueous dilution remains stable for several days.

The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label 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.
