POLYESTERIC VARNISH FOR INSULATING ELECTRIC WIRES.

摘要

Aim of the present invention is the preparation of a varnish that will insulate the "bare" electric wires in cases where the conventional plastic insulation is not effective. The insulation is achieved by an initial immersion of the wire in the varnish and then heating at a specific temperature for a specific time. The said insuated wires can be used in the manufacturing of coils or in the windings of electric motors. The specific varnish, after experimentation, was found to meet all the desired requirements.
