POLYETHERIMIDE-POLYISOCYANATE ENAMEL AND ELECTRICAL CONDUCTOR INSULATED THEREWITH

摘要

60IN-591 Electrical conductors such as magnet wire and magnet strip are insulated with a cured coating deposited from an enamel comprising a polyetherimide and a blocked polyisocyanate, optionally including aliphatic amino compounds, phenolic resins, titanate esters or a mixture of any of the foregoing. In comparison with unmodified polyetherimides, superior cutthrough resistance is imparted to the coated conductors by the enamels of this invention.
