SILFOAM® SE 2262

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
• Antifoams

Processing

• 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.
