Aluminum-Filled High Temperature Resins


Aluminum-filled epoxy casting resins (dark gray in color) are not as heavy as iron-filled systems, 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.
