J-B Weld is the Original Cold Weld. It is a two-part epoxy system that creates strong, lasting repairs. With a 1:1 mixing ratio, it forms a permanent bond that can be shaped, tapped, filed, sanded, and drilled after curing. It sets in 4-6 hours to a dark gray color and fully cures in 15-24 hours for a hard bond. This product boasts a tensile strength of 6220 PSI and can withstand temperatures up to 550°F once fully cured.
