    Compare epoxy, acrylic, and urethane adhesive options. Then learn about adhesive performance measures and best practices to create a strong bond.

    Quick-Set Epoxy Structural Adhesives

    Cartridge

    For quick repairs, these epoxies begin to harden in six minutes or less. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal.
    These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.
    Paste—Thicker than liquid adhesives but still spreadable—good for filling gaps and covering surfaces.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

    Epoxy Potting Compounds

    Encase electronic assemblies in a layer of epoxy for protection from dust, chemicals, moisture, mechanical shock, and vibration. The strongest of the potting compounds, epoxies are rigid and wear resistant. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. All require a mixer nozzle and gun to dispense.

    Optically Clear Epoxy Structural Adhesives

    Image of Product. Cartridge. Front orientation. Cartridge.

    Cartridge

    For invisible bond lines, these adhesives dry clear. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal. Choose an epoxy that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.
    These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.
