  • Additive for improving the solvent resistance and other properties of water-based binder systems
    Patent number: 8865818
    Abstract: Aqueous dispersions which comprise nanoscale ZnO particles and nanoscale particles of a non-ZnO metal oxide, semimetal oxide or oxo salt are used in aqueous binder systems, such as coating materials, adhesives, sealants and binders, to improve the solvent resistance of the dried or cured binder system, and to improve other properties.
    Type: Grant

  • Zinc oxide particles which have been modified with phosphonocarboxylic acid and use of zinc oxide particles
    Patent number: 8791191
    Abstract: Nanoscale ZnO particles are used in aqueous binder systems for increasing the blocking resistance, for reducing the drying time and/or for increasing the resistance to chemicals, detergents, heat, weathering or biological assault on the dried or cured systems. Described further more are nanoscale zinc oxide particles surface-modified with phosphonocarboxylic acid, and their use.

  • CHEMOMECHANICAL MANUFACTURE OF FUNCTIONAL COLLOIDS
    Publication number: 20110288183
    Abstract: A method for producing a functional colloid during which particles are reactively fragmented in a mechanical manner in a dispersant in the presence of a modifying agent so that the modifying agent is chemically bound, at least in part, to the fragmented colloid particles.
