ABSTRACT
Studies were presented on the ways surface character of colloidal silica (SYLOID®244) can be altered from a hydrophilic to hydrophobic using natural latex milk. Effects of concentration and volume of the applied latex emulsion, LATEKS KAGETEX®FA, were examined on structure of hydrophobic silicas and their physicochemical properties, including bulk density, capacities to absorb water, dibutyl phthalate and paraffin oil. Sedimentation rate and wettability with water were also examined for the modified and unmodified silicas.
