摘要
A high solids content, low molecular weight polymer, low viscosity polyamide-imide enamel is described. The enamel is a reaction product of polyisocyanate, trimellitic anhydride, and an isocyanate blocking alcohol having a ratio of free isocyanate to total carboxyl and anhydride groups of 0.99:1 to 0.85:1. The method of making the enamel and the method of coating electrical conductors such as magnet wire with such enamel are also disclosed.
