RS-2299 Lead Free X-Ray Material

RS-2299 Lead Free X-Ray Shielding Epoxy Resin

RS-2299 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 greater than 20% of the x-ray shielding of lead metal, and is equivalent or better than industry standard 30% lead oxide filled “orange” epoxy. This material is non-hazardous, and meets UL94V-0 flammability requirements.
