PolyPoxy® 7136 Casting Epoxy

SKU:
BCBC7136GALKIT

PolyPoxy® 7136 is a two-component, room temperature curing (RTV), 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. This aluminum-filled epoxy is typically used for heat-resistant tooling, vacuum form tools, injection and compression molds, RTM and RIM molds, and matched dies. 

PolyPoxy® 7136 has a pot life of 85 minutes, a demold time of 24 hours, and cures to a Shore D90 hardness. For a similar product with a longer pot life, consider PolyPoxy® 7136-2 Casting Epoxy

For service temperatures between 150°F and 300°F, a post-cure is required.

WARNING: This product can expose you to chemicals including Epichlorohydrin which is known to the State of California to cause cancer and/or reproductive harm. For more information, go to www.P65Warnings.ca.gov
