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.
