Abstract:
A superconducting wire comprising a superconducting core and a metal sheath surrounding the core, said sheath having at least one dielectric coating thereon which is functionally capable of providing and maintaining coating integrity and insulative and protective functions during exposure of the coated wire to cycling of temperature variations from ambient levels to superconductive operating temperatures of at least as low as 77.degree. K., said coating being composed of a radiation-cured composition resulting from a formulation comprising:(a) at least one (meth)acrylate terminated urethane oligomer;(b) at least one (meth)acrylate functionalized acidic adhesion promoter;(c) at least one (meth)acrylate reactive diluent; and(d) at least one free radical photoinitiator.
