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 Will not crack when drilled and great for interior or exterior projects One-time application that dispenses equal amounts of each component every time Can be used for sealing electrical components that will not conduct electricity
