ABSTRACT:
A radiation curable coating composition for superconducting wires including at least one (meth)acrylate terminated urethane oligomer, at least one adhesion promoter, at least one (meth)acrylate functionalized diluent and at least one free radical photoinitiator. The coating composition is able to withstand repeated thermal cycling from the ambient temperature to the critical temperature of the superconducting wire and, because the composition is radiation cured, the superconducting wire is not heated, thus avoiding degrading the superconducting wire.
