Abstract

A procedure to prevent the agglomeration or re-agglomeration of fine particle powdery substances, by adding widely dispersed silicic acid, characterized by the addition of active silicic acid to the substances to be protected, during or after their manufacture, or before their application. highly dispersed hydrophobic, obtained synthetically, possibly mixed with highly dispersed hydrophilic active silicic acid, obtained synthetically.
