Polyamide-imide resin insulating coating material, insulated wire and method of making the same

A polyamide-imide resin insulating coating material, which is obtained by reacting an isocyanate component with an acid component, has a main solvent component of γ-butyrolactone. In the coating material, a total compounding ratio of 4,4′-diphenylmethane diisocyanate (MDI) and trimellitic anhydride...

Beschreibung
Zusammenfassung:	A polyamide-imide resin insulating coating material, which is obtained by reacting an isocyanate component with an acid component, has a main solvent component of γ-butyrolactone. In the coating material, a total compounding ratio of 4,4′-diphenylmethane diisocyanate (MDI) and trimellitic anhydride (TMA) is 85 to 98 mol %, where the total compounding ratio is given by averaging a compounding ratio of MDI to the isocyanate component and a compounding ration of TMA to the acid component.
