Soleron coated magnet wire is now available in 4oz. spool. Gauge-12. 12 feet, 155DegC, NEMA MW 80-C. Soderon® combines the magnet wire insulation characteristics of polyurethane with the advantages of a polyamide (nylon) topcoat. With the nylon, Soderon® is still readily solderable, yet the solvent resistance and thermal stability of the insulation is excellent. In addition, the nylon improves windability and tolerates more severe winding operations. Soderon® is an excellent choice for automatic winding machines.
