Tego Antifoam 2-57 Organo-modified siloxane Degussa-Goldschmidt Defoamers / Anti-Foaming Agents Surfactants Surfactants >> Silicone based ADHESIVE >> Water-based TEGO ® Antifoam 2-57 TEGO ® Antifoam 2-57 is an antifoam emulsion based on organo-modified siloxanes. TEGO ® Antifoam 2-57 provides reliable foam control and excellent long-term efficiency particularly in polymer dispersions and emulsions and may therefore be used for foam control in a variety of industrial applications: as a processing aid for water based polymerization of thermoplastics and elastomers* in the processing and application of polymer dispersions/latices* Due to the special raw material basis TEGO ® Antifoam 2-57 combines excellent efficiency with maximum compatibility at the same time. This results in a unique product profile which cannot be achieved either with organic or with traditional silicone oil based antifoams. Furthermore undesirable effects associated with silicone based antifoams (silicone spotting, fish eyes) can be eliminated in most applications. TEGO ® Antifoam 2-57 is easy dispersible in water and may therefore be applied as delivered. However, in most applications it is beneficial to apply TEGO ® Antifoam 2-57 pre-diluted in water (1 : 1 to 1 : 10). Depending on the application in question the required dosage may vary over a wide range (0.05 - 0.2 %); suitable screening tests are therefore recommended (initial dosage: 0.1 %). Emulsion based on organo-modified siloxanes. Used as antifoam in water-based adhesives. Provides reliable foam control and very good long-term efficiency in polymer dispersions and emulsions. Possesses very good compatibility and undesirable effects associated with silicone based antifoams (silicone spotting, fish eyes) can be eliminated in most applications. Use level: 0.05-0.2 %.
