Application
SILFOAM® SE 1661 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 degassing
  • Manufacture and processing of polymer dispersions for textiles, paper, paints and surface coatings<(>,<)> as well as adhesives
  • Cooling lubricants
  • Textile formulations


Due to its raw material composition, SILFOAM® SE 1661 is suitable for direct food contact and as a processing aid in fermentation processes.

SILFOAM® SE 1661 shows a very good foam control performance in plant protection formulations (e.g. in surfactant rich agrochemical formulations).

ProcessingIn 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. SILFOAM® SE 1661 is best added as it is. Metering pumps should have low shear stress. The amounts added usually are in the range from 0.02 to 0.5 %. However, the optimum dosage should be determined in preliminary tests.
 

Storage

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.
