Abstract

The invention relates to a coating material comprising condensates of at least one compound (A) of the general formula RaMZb (a=0-3; b=1-4; a+b=3, 4), where R is a non-hydrolyzable organic group, and at least one compound (B) of the general formula R′xMZy(x=1-3; y=1-3; x+y=3, 4), where R is a non-hydrolyzable organic group and at least one R′ contains a perfluoro polyether structure separated from M by at least two atoms, where M is an element from the periodic table of elements selected from the main groups III-V or from the subgroups II-IV and Z is a hydrolyzable organic group, and where at least one R is not equal to at least one R′.
