Fire-Retardant Epoxies

PRO-SET fire retardant epoxy resins are paired with previous-generation PRO-SET M2043, M2044, and M2046 Hardeners to control cure speed rather than the LAM or INF hardeners in our New Standard PRO-SET product line. These hardener formulations are still available to order.

PRO-SET XR28A Resin is a low-viscosity, fire retardant resin for the manufacture of composite laminates and is compatible with vacuum infusion processes.

PRO-SET XR29A Resin is a thixotropic, fire retardant resin that works well for hand wet out or use in an impregnating machine.
