The electonics and the field coils were encapsulated in a UL recognized, MIL-I-46058C polyurethane. A synthetic grease, used on Mil/Aero Fans, has been added to the bearing shields and shaft to prevent corrosion. Polyurethane was also brushed on the stator to retard corrossion. Fans may have some residue of conformal coating that does not affect performance
