| 摘要 |
<p>The invention relates to the use of polysilazanes as a permanent coating on metal and polymer surfaces for preventing corrosion, increasing scratch resistance and to facilitate easier cleaning. The invention comprises a solution of a polysilazane or a blend of polysilazanes of the general formula 1—(SiR′R″—NR′″)n— (1) where R′, R″and R′″are identical or different and independently of one another represent hydrogen or an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl group and n represents a whole number and is calculated in such a way that the polysilazane has a numerical average molecular weight of 150 to 150 000 g/mol, in a solvent. The invention also relates to a method for producing the coating.</p> |
