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.  Recommended on:  Bonding metal and concrete as well as glass, ceramic and wood Repairing machinery, appliances, tools, lawnmowers, automotive components, pipes, embedding bolts and screws into metals, concrete or stone and sealing electrical components against moisture and vibration High impact resistance: will not crack when drilled Water resistant   Great for interior or exterior projects Will not shrink   One-time application Convenient double syringe   Dispenses equal amounts of each component every time Will not conduct electricity  Can be used for sealing electrical components Sets in 5 to 12 minutes  Quick completion of project
