摘要：A coating for metal surfaces, consisting of a.) optionally, a scratch-resistantperhydropolysilazane base coat and b.) an upper protective layer containing at least oneperhydropolysilazane of formula (1) and photocatalytic titanium dioxide (I), wherein n is awhole number and n is dimensioned in such a way that the perhydropolysilazane has anumber average molecular weight of 150 -150.000 g/mol. Preferably, the thickness of theprotective layer is at least 1 micrometre, more preferably 2 - 20 micrometres. Theinvention also relates to a method for the production of the coating, in addition to theuse thereof as a self-cleaning protective layer, particularly for the rims of automobiles.
