Material Notes:

BC 7020 is a lightweight two component epoxy backfill system. Unlike BC 7010, the filler portion is pre-blended into the resin and hardener components for easier handling, thus simplifying the mixing process. BC 7020 is ideally suited for foundry applications involving mold and core construction. Features: low cost, simple mix ratio (1 to 1 by wt.), long pot life, machineable low shrinkage, and color change to insure complete mix.Information provided by BCC Products, Inc.
