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).
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. 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.
