Compare epoxy, acrylic, and urethane adhesive options. Then learn about adhesive performance measures and best practices to create a strong bond.
Optically Clear Epoxy Structural Adhesives
 |
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.
