BeadFix 2 Part Epoxy is a single use epoxy that eliminates the need for measuring. Simply empty both tubes completely onto a mixing surface (aluminum foil or heavy paper to be discarded after use) mix the two parts together fully and begin gluing. 2 part epoxy is the strongest bond for most gluing applications. Make certain that all parts to be glued are prepped and ready before mixing the epoxy. Pot life (amount of time before adhesive sets up and can no longer be used) is approximately 20 minutes.
