An enameling lacquer comprises a base first polymer and a copolymer which is compatible with said first polymer and which contains polymeric chains selected from polysiloxanes, fluorated chains and alkane chains. The lacquer is of particular application to an enameled wire comprising at least one layer of an enamel obtained by reticulation of the lacquer.

Enameling lacquer, process for the manufacture of the lacquer and application of the lacquer to enameling wires

The enamelling apparatus includes at least one assembly constituted by an applicator for applying varnish on a conductive wire and an associated enamelling oven, with the wire passing through both of them. The enamelling oven has a single chamber filled internally with radiant heater elements facing the path of the wire and the atmosphere inside the chamber is controlled to have an oxygen content that is low, and less than 6% . The apparatus is suitable for use in the production of an enamelled wire.
