Abstract

A coating composition is disclosed based on polycondensates of hydrolyzable compounds in particular of Si, Al, Ti and/or Zr, whereas at least part of the non-hydrolyzable groups linked to these elements contain in average 2 to 30 fluorine atoms linked to aliphatic carbon atoms. A process for producing such coating compositions is also disclosed. The corresponding cured (transparent) coatings are characterized in particular by a very good adherence to various types of substrates, in particular glass, besides an antiadhesive effect with respect to many different materials.
