Loctite epoxy metal/concrete is a two-part system consisting of an epoxy resin and a hardener. The convenient syringe dispenses equal amounts of each component every time. When mixed in equal volumes, resin and hardener react to produce a tough, rigid, high strength bond in 5 to 12 minutes. It is used as an adhesive for repairing, filling and rebuilding all metal and concrete surfaces. Loctite epoxy metal/concrete does not conduct electricity which is ideal for sealing electrical components. It cures to a metallic gray finish and can be easily sanded or machined. It does not shrink and is resistant to water and most common solvents.
