Abstract:
Flaked or plate-like materials that contain silicate were found to be useful as bases for the manufacture of defoaming compositions. Hollow microspheres with largely siliceous surfaces are crushed to form flaked fragments which are rendered hydrophobic by coating with a silane or silicone. The hydrophobized fragments are then dispersed in a water insoluble organic liquid to complete preparation of the defoamer. Especially useful are hollow microsphere fragments containing sodium silicate and a polysalt.
