RS-2277 Lead Free X-Ray Shielding Material

RS-2277 Lead Free X-Ray Shielding Epoxy Resin

RS-2277 is a patented, castable, lead free insulating grade filled epoxy resin specifically designed for high voltage insulator applications requiring X-Ray shielding. This material provides good electrical grade insulation properties, high mechanical properties, and superior arc resistance to any lead oxide filled epoxy. This material has equal x-ray shielding to a 25% lead oxide filled epoxy. This material is non-flammable and meets UL94V-0 requirements.
