LOCTITE Epoxy Weld Bonding Compound is a two-part system consisting of an epoxy resin and a hardener. When mixed in equal volumes, the resin and hardener react to quickly produce a tough, rigid, high strength bond. Loctite Epoxy Weld can be used as a convenient alternative to welding. It can be used as an adhesive for repairing, filling and rebuilding all metal and common surfaces. It cures to a metallic grey finish and can be easily sanded, drilled, machined or painted when fully cured. Loctite Epoxy Weld does not shrink and is resistant to most shop fluids such as water, diesel fuel, gasoline, antifreeze, hydraulic fluid, motor oil and transmission fluids.
