COATING HAVING HIGH CORONA RESISTANCE AND PRODUCTION METHOD THEREFOR

摘要

A coating for a polymeric insulating material, includes 1 to 10 layers, each of the 1-10 layers having a coat thickness in a range from 0.1 to 100 μm and being wet-chemically produced from at least one precursor selected from the group consisting of silane, siloxane and silicate. The coating is silicatic and includes a silicatic base unit with organic radicals at a ratio so as to enable application of the coating onto flexible substrates.
