Aluminum-Filled Room Temperature Resins

Aluminum-filled epoxy casting resins (gray in color) are not as heavy as iron-filled systems and are more readily machinable.

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 for your project.
