Nylon is a magnet wire overcoat used:
- To improve chemical resistance when applied over polyurethane and polyesterimide base coats
- To improve wire windability in coiling operations (when used also with any of SPC’s self-bonds)
- To reduce the coefficient of friction during insertion processes. This last benefit is found most useful in thermocouple manufacturing processes
This coating is not intended to provide any benefit to electrical performance in coated wire products.
Data below represents typical wire properties when Nylon is used as an overcoat with a polyurethane basecoat (MW83-C) or a polyesterimide base coat (MW78-C).
