ABSTRACT:
A magnet wire suitable for use in hermetic motors comprising a conductor wire, an insulating intermediate layer, a polyamide outer layer, and an organic polymeric lubricant coating on the outer layer. The lubricant has a pour point below about 15.degree. F. (-9.degree. C.) and wets the outer layer. A preferred lubricant is soluble in monochlorodifluoromethane and in dichlorodifluoromethane, and comprises a saturated C.sub.2 -C.sub.4 ether of ethylene oxide and 1,2-propylene oxide copolymers. A particularly preferred lubricant has a viscosity of about 100 to 400 SUS (21 to 87 centistokes) and a pour point of about -60.degree. F. (-51.degree. C.).
