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.
