J-B Weld is the original and world's finest cold-weld two-part epoxy system that provides strong, lasting repairs to metal and multiple surfaces. It is the solution when welding or soldering is not an option due to cost, downtime, or environmental concerns.

J-B Weld is a two-part epoxy resin when mixed at a ratio of 1:1, it forms a compound as tough as steel. It forms a permanent bond and can be shaped, tapped, filed, sanded, and drilled after curing. You can use it as adhesive, laminate, plug filler, sealant, or electrical insulator. At room temperature, it sets in 4-6 hours to a dark grey color. A full cure is reached in 15-24 hours. It is waterproof, and resistant to petroleum, chemicals, and acids. It can also withstand shock, vibration, and temperature up to 550ºF when fully cured. Extremely powerful, non-toxic, and cleans up with soap and water before setting.
