COATING COMPOSITION COMPRISING POLYSILOXANE-MODIFIED POLYURETHANE FOR SOFT-FEEL, STAIN RESISTANT COATINGS

摘要

The invention relates to a 2K coating composition comprising a polysiloxane-modified polyurethane and a hardener, wherein the polysiloxane-modified polyurethane obtainable by a method comprising the following steps: a) subjecting a polyol to a reaction 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 hydroxyl-functional polysiloxane, to obtain the polysiloxane-modified polyurethane.The polysiloxane-modified polyurethane can be used in a coating composition to form a coating which has smooth feel, stain resistance and easy clean properties, particularly desired in the field of e.g. consumer electronics and automotive industry.
