WATER-SOLUBLE ORGANOSILICONATE POWDER

摘要

Organosilanolate powders having a low cation to silicon ratio provide superior hydrophobing ability. The powders may be prepared on an industrial scale by hydrolysis of a silane with a basic salt solution, adding an inert organic solvent, and removing gaseous or alcoholic hydrolysis products by evaporation or distillation, precipitating the organosilanolate as a fine powder.
