Iron-Filled Epoxy Casting Resins


Iron-filled epoxy casting resins (black in color) are heavy, highly wear-resistant compounds that are suitable for foundry patterns or thin-gauge metal-forming tools.

Epoxy casting resins generate heat (exotherm) during the curing process. This heat can become excessive if the epoxy is poured thicker than the suggested casting thickness, causing warping, cracking and/or brittleness. Therefore, be careful to choose the correct system to pour your part.
