Abstract
A coating for surfaces, comprising at least one of the polysilazanes having the formula 1 and/or formula 2 where n is an integer and is dimensioned such that the perhydropolysilazane has a number-average molecular weight of 150 to 150 000 g/mol, a solvent and a catalyst and, if desired, one or more cobinders, for preventing scaling and corrosion on metal surfaces. The hardened coating has a thickness of 0.2-10 micrometers, preferably 0.3 to 5 micrometers. It is particularly useful as a protective coating for metals for preventing scaling and corrosion.
