Abstract
The object of the present invention is to provide antifoams which have a good antifoam effect in aqueous dispersions of polymeric organic substances, cause no wetting defects when these dispersions are applied to a surface and at the same time retain their antifoam activity even after prolonged storage at temperatures down to the freezing point.
