J-B Weld™ is the original cold weld two part epoxy system that provides strong, lasting repairs to metal and multiple surfaces. 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 t o6 hr to a dark gray color. A full cure is reached in 15 to 24 hr. J-B Weld™ has a tensile strength of 3960 psi and sets to a hard bond overnight. It can withstand temperatures up to 550 deg F when fully cured.
