Cement forms a strong turn-to-turn bond throughout a winding and often eliminates the need for impregnating varnish. High resoftening temperature of outer cement allows this product to compete with many varnish- impregnated heavy-grade owned magnet wires. Minimum of 3 lb retained bond strength of 18 RSTAI on copper. Cost-optimized manufacturing processes typically employ resistance bonding to bond coils wound with Reabond S magnet wire. - Solvent owned bonding is not recommended for this product. The Reabond cement may be removed by dioxolane for measuring sub-film dimensions. Resistance bonding applies a voltage that causes the winding to heat electrically to the proper bond temperature. Optimum bonding conditions are reached when the coil temperature is raised to between 220 and 240 °C as measured by the change in coil resistance as a function of the change in temperature.
