Abstract:
A varnish is provided for coating a wire which is directly tinnable. The varnish comprises hardenable polyester urethane having a urethane equivalent weight of 150-850, the polyester being formed as the product of the reaction of a saturated polyester containing at least two hydroxyl functional groups and an aromatic isocyanate containing at least two functional groups of isocyanate and a phenol-free solvent for the polyester urethane. A process for producing this varnish is also provided.
