Abstract
An improved thermally stable, lubricious magnet wire enamel is disclosed which is particularly suitable for use as an outermost insulating, lubricating layer on a magnet wire substrate. The enamel comprises the reaction product of a tri-basic acid anhydride, a diisocyanate and a polyfunctional organosiloxane. The coating has a coefficient of friction, after application to magnet wire, of less than 0.10. It is also substantially all polyfunctional organosiloxane reacted, i.e. substantially no polyfunctional organosiloxane is capable of being extracted from the cured coating with organic solvents.
