Epoxy Casting Resins
Freeman and Huntsman Advanced Materials offer a broad, diverse line of pourable epoxy casting resins for the production of foundry patterns, core boxes, molds, fixtures, and tooling.

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. Aluminum-filled epoxy casting resins (gray in color) are not as heavy, are more readily machinable, and are available with higher temperature resistances. 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.
