J-B Original is designed to be an alternative to welding, soldering and brazing. This epoxy bonds to most clean surfaces, and it will set in as little as 4 to 6 hours and fully cure in 24 hours. J-B Weld is waterproof and resistant to petroleum, chemicals and acid. It can be drilled, machined, painted, sanded and filed once it's cured. J-B Weld is nontoxic and temperature resistant up to 600F.
