Abstract

Heat-curable hot-melt enamels, a process for their preparation, and the production of highly heat-resistant wire windings. These heat-curable hot-melt enamels are solutions of a nylon in organic solvents, which contain, as the nylon, a nylon possessing functional amino groups and additionally contain a blocked di- or polyisocyanate. They are useful for the production of highly heat-resistant wire windings.
