ABSTRACT:
This invention relates to high solids aqueous dispersions of reactive hydrophobizing agents, to methods of preparation of such dispersions, and to aqueous blends of such dispersions with a variety of other aqueous dispersions or solutions, including synthetic resin emulsions, wherein the aqueous dispersions of reactive hydrophobizing agents are prepared in the presence of a water-soluble protective colloid in combination with a solid water-insoluble anhydride compound. The dispersions of this invention efficiently impart hydrophobic characteristics to the surfaces and interfaces of materials onto which they are applied and unexpectedly exhibit very high stability to storage and handling conditions found in industry.
