REBCO coil is a promising technology for propulsion motor. Although degradation was discovered in epoxy impregnated coil, it is essential to fill the coil with epoxy in such occasion. This paper describes preparation of epoxy-impregnated REBCO coils with tapes from three different Manufacturers. All the coils were tested both before and after epoxy impregnation, consistency of Ic value and high n-value suggest that there's no degradation in these coils. The epoxy-impregnated REBCO coil can go though fast cooling and warming processing five times without degradation, which also assured the high quality of the coils.
