The present invention relates to a 2K coating composition comprising a polysiloxane-modified polyurethane and a hardener, wherein the polysiloxane-modified polyurethane is obtainable by a process comprising the steps of: a) reacting a polyol with an isocyanate functional silane coupling agent , to obtain a silane-grafted polyol, and b) subjecting the silane-grafted polyol to a condensation reaction with a hydroxy-functional polysiloxane to obtain a polysiloxane-modified polyurethane. The polysiloxane-modified polyurethanes can be used in coating compositions to form coatings with smooth feel, antifouling, and easy-cleaning properties that are particularly desirable in, for example, the consumer electronics and automotive industries. |
