Aqueous fluoromodified polyurethane system for anti-graffiti and anti-soiling coatings

摘要

An aqueous fluoromodified polyurethane system for one- or two-component anti-graffiti and anti-soiling coatings is prepared by (a) preparing a binder component based on an aqueous solution or dispersion of optionally hydroxy- and/or amino-functional oligourethanes and/or polyurethanes having fluorinated side chains, and, optionally, (b) subsequently reacting the binder component with a crosslinker.
