HPX-850 Backfill System

HPX-850 is a lightweight, heat-resistant, two-component epoxy back-fill system. Like BC7020, the filler portion is pre-blended into the resin and hardener components for easier handling, thus simplifying the mixing process. The advantages of HPX-850 include low cost, long pot life, machineability, and low shrinkage. HPX-850 is ideally suited for numerous applications involving mold and core construction.
