Abstract

The subject of the invention is a water-based coating composition comprising at least one polyurethane dispersion, at least one polyisocyanate and at least one polysiloxane hybrid dispersion, whereby the weight ratio between the solids content of the polyurethane dispersion and the solids content of the polysiloxane hybrid dispersion is 25/75 to 75/25. The water-based coating composition is very elastic with a high strength at high elongation together with a high gloss and good resistance against harsh ambient conditions. It is particularly suitable for the waterproofing of a low slope roof without the need to be overcoated with a topcoat.
