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.
