Mixed at a ratio of 1:1, it forms a permanent bond and can be shaped, tapped, filed, sanded and drilled after curing. At room temperature, J-B Weld™ sets in 4-6 hours to a dark grey color. Full cure is reached in 15-24 hours. J-B Weld™ has a tensile strength of 5020 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550⁰ when fully cured. Review: Sets rock hard for a solid strong bond - Bought this epoxy adhesive to glue magnets onto my front door letterbox which was rattling during recent high winds. The magnets, now securely in place, allow a firm grip of the outer flap without the postman noticing the additional effort required in lifting the flap for mail. The epoxy resin fixes metal to metal and is completely cured within 12-18 hours. I had to take care that only the magnets were glued to the metal parts of the letterbox as any overspill would have resulted in the letterbox being totally sealed as this resin sets rock solid.
