Abstract
A coating composition including at least one water-based anionic polyurethane dispersion and 0.1 to 4 weight-% of nanoparticulate TiO2 having an average particle size of not more than 100 nm, based on the solids content of the coating composition. The cured coating composition is suitable as a top coat in a decorative multilayer coating system including at least one polyurethane base coat. The multilayer coating system exhibits improved non-yellowing property and cleanability. The liquid multilayer coating system is particularly suitable for balcony applications.
