High-Performance, Aluminum-Filled Epoxy for Casting Applications
PolyPoxy® Casting Epoxies are pourable, aluminum-filled, heat-resistant, room temperature curing (RTV) epoxy resin systems that are typically used for heat-resistant vacuum form tools, injection and compression molds, RTM and RIM molds, and matched dies.
PolyPoxy® 7136 is a heat-resistant casting epoxy that can be cast to a thickness of ¾” in non heat-conductive molds and 1.25” in heat-conductive molds. For service temperatures between 150°F and 300°F, a post-cure is required.
PolyPoxy® 7136-2 is a heat-resistant casting epoxy that may be cast up to a thickness of 2” in non-conductive molds or 3” in conductive molds. For service temperatures between 150°F and 300°F, a post-cure is required.
