    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.
    Model Number HY4090—A blend of epoxy and instant-bond adhesive for a balance of strength, cure speed, and temperature resistance.
    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.

    Take your time to precisely align parts before bonding, and maintain flexibility afterward. These adhesives won't harden until you expose them to a compatible light source. They also remain elastic so the bond can bend without breaking.
    Thin Liquid—Seep into narrow gaps and joints that thick-liquid adhesives can't reach. Use when bonding close-fitting parts.

    With excellent resistance to corrosive chemicals, these epoxies maintain bonds in tough conditions.
    Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal. Choose an adhesive that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.

    Even in enclosed or poorly ventilated spaces, these epoxies form bonds without the noticeable odor other structural adhesives leave behind.
    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.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.
