ABSTRACT:
UV-curable urethane-acrylate resin systems of improved thermal stability in the cured state are provided, the resins being of polyurethane acrylate, polyurea acrylate, and/or polyurethane/polyurea acrylate composition and being thermally stabilized by the addition of a combination of stabilizers which includes a hindered piperidine derivative and a hindered phenol derivative. The stabilized resin systems, useful for example for the protective coating of glass optical fibers, retain their rapid UV curing characteristics.
