System, useful for coating a substrate e.g. concrete and plasterboard, comprises a top coating that is obtained from a composition of synthetic resin dispersion and intermediate coating based on cationic polymer dispersion

摘要

Coating system (I) comprises a top coating and an intermediate coating, where the top coating is obtained from a composition that has a pH of at least 9 and comprises a synthetic resin dispersion and the intermediate coating is based on a cationic polymer dispersion. An independent claim is included for a process for preparing (I) comprising applying the intermediate coating on a substrate, and applying the composition of top coating on the intermediate coating.
