摘要：
The invention relates to an optionally fluorinated polyurethane-polymer hybrid dispersion with enhanced surface properties (low critical surface stresses Ϝc and a very high contact angle θ), which is obtained by: a) producing a dispersion component (binding agent) based on an aqueous solution or dispersion of an optionally hydroxy and/or amino-functional polyurethane-polymer hybrid with optionally fluorinated side chains and optionally b) subsequently reacting the dispersion component from step a) with a crosslinking component (D). The inventive polyurethane-polymer hybrid dispersion can be produced with very little or no binding agent and with a high solids content, while requiring very few stabilized groups.
