  • Stable high solids aqueous dispersions of hydrophobizing agents
    Patent number: 5658377
    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.

  • High solids aqueous dispersions of hydrophobizing agents
    Patent number: 5403392
    Abstract: Stable high solids aqueous dispersions of hydrophobizing agents can be prepared utilizing plant glycosides as the primary dispersion stabilizer and, optionally, secondary 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.
