| abstract |
The invention relates to the use of polysilazanes as permanent coatings on metal surfaces for prevention of the susceptibility to fingerprints, characterised in that the polysilazane is in the form of a solution of a polysilazane or a mixture of polysilazanes of general formula 1 -(Si R' R"-N R'")<SUB>n</SUB>-, where R', 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 150 to 150,000 g/mol in a solvent. The invention further relates to a method for production of the coating. |
