Poly 180B is a Thermal Class 180 polyurethane wire enamel that meets the requirements of NEMA MW1000, 82-C or 83-C (when applied with a Nylon overcoat, Poly 180B/Nylon). The Nylon top coat is applied to reduce the coefficient of friction during winding and/or insertion.
This coating combination can be applied as a basecoat when self-bonding magnet wire is required for a customer’s specific coil winding/forming operation.
Poly 180B/Nylon can be soldered without the use of flux (on copper substrates), and solderability times are greatly reduced with this coating combination versus products that have been coated with Tri-2-sod.
