RS-2295 Lead Free X-Ray Shielding Epoxy Resin

RS-2295 is a patented, high density filled, castable, lead free insulating grade epoxy resin specifically designed for high voltage insulator applications requiring X-Ray Shielding. This material provides 20% of the X-Ray Shielding of lead metal, and is equivalent to industry standard 30% lead oxide filled “Orange Epoxy”. This material is non-hazardous and can be processed, machined and disposed of as a non hazardous material. This material also meets UL94V-0 flammability rating.
