The invention relates to fluorine-modified reactive resin systems having improved surface properties which comprise a) 100 to 300 parts by weight of a binder component (A), capable of polyaddition and/or polycondensation, said binder component (A) having a solids content of 5 to 95 % by weight of the polymer, b) 5 to 100 parts by weight of a functionalizing component (B), capable of polyaddition and/or polycondensation and having a molar weight of 100 to 10.000 Dalton and a fluorine content bound to the polymer of 10 to 90 % by weight, c) 0 to 100 parts by weight of a curing agent component (C) capable of polyaddition and/or polycondensation and having a molecular weight of 100 to 10.000 Dalton, and d) to 300 parts by weight of a formulation component (D), whereby component (A) may contain component (B) optionally in a polymer-bound form. It was surprisingly found that fluorine-modified reactive resin systems cannot only be used for hard coating systems or surfaces having very low critical surface tensions ?<SUB>c</SUB> and very high contact angles ?, but that these systems have a substantially reduced dirt pickup behavior as compared to prior art systems. |
