USE OF POLYSILAZANES FOR COATING METAL STRIPS

摘要

A coating for metals containing a polysilazane solution or a mixture of polysilazanes of the general formula (I)—(SiR′R″-NR′″)n—  (1) wherein R′, R″and R′″are identical or different and independently represent hydrogen or an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl radical, wherein n is a whole number and n is dimensioned in such a way that the polysilazane has a number-average molecular weight of 150 to 150 000 g/mol, in a solvent and at least one catalyst. The invention also relates to a method for the production of the coating.
