Reabond A Nysol single build is a dual film solderable insulation composed of modified polyurethane resins with a polyimide (nylon) overcoat. The nylon overcoat provides a significant reduction in the wire's coefficient of friction aiding both windability and the production of compact coils. - Reabond A Nysol single build has a continuous operating temperature of 155 °C and is formulated for applications where a solderable insulation is desired.
