RS-2244 – NO TRACK EPOXY RESIN
RS-2244 is a castable, filled epoxy resin specifically designed for high temperature high voltage insulator applications. This material provides excellent electrical grade insulation properties, high mechanical properties, and chemical resistance. This material is unique in that it will not char when exposed to a high voltage arc as compared to standard electrical grade epoxy materials which will leave a carbon char mark. In addition, this material is non-flammable and meets ul 94/v-0 requirements.
