The invention relates to the use of polysilazanes as permanent coatings on metal surfaces for the prevention of the susceptibility to fingerprints, characterized in that the polysilazane is in the form of a solution of a polysilazane or a mixture of polysilazanes of the general formula 1 <?in-line-formulae description="In-line Formulae" end="lead"?>-(SiR'R''-NR''')<SUB>n</SUB>- (1)<?in-line-formulae description="In-line Formulae" end="tail"?> where R', R'', R''' independently=H, optionally-substituted alkyl-, aryl, vinyl- or (trialkoxysilyl)alkyl, n=a whole number such that the polysilazane has a number-average molecular weight of from 150 to 150,000 g/mol in a solvent. The invention further relates to a method for production of the coating. |
