Abstract
Stable high solids aqueous dispersions of hydrophobizing agents can be prepared utilizing combinations of water-soluble protective colloids in combination with hydrolytically stable water-insoluble organic compounds selected from the group comprising organic salts and polar group-containing organic compounds as dispersion stabilizers. These dispersions impart water repellent characteristics when applied to the interfaces and surfaces of materials, and are compatible when blended with synthetic resin emulsions.
