Abstract

Pulverulent alkali metal alkyl siliconates having lesser hydroscopicity and improved hydrophobicity in construction materials are produced by spray drying an aqueous solution of an alkali metal alkylsiliconate having a defined range of alkali metal content, a low alcohol content, and a low chlorine content.
