Abstract
Abstract A selfbonding magnet wire is disclosed having an outer bondable coating of nylon 612. In addition to improved bonding properties, the magnet wire has improved moisture resistance and solvent resistance so as to be useful in hermetic motor environment. Overcoated with appropriate external and/or internal lubricant, it can also be power inserted in locking wire size range. The nylon 612 can be used as a sole insulation coat or part of a multicoat system, for example, overcoated on polyester or polyamideimide overcoated polyester. The nylon 612 can also be used as a blend with nylon 11.
