Structural Adhesive

Structural adhesive carries load across a joint and replaces or supplements welding, rivets and screws. It spreads stress over the whole bonded area instead of concentrating it at a few fasteners, which improves fatigue life and allows thinner, lighter materials to be joined.

Selecting a structural grade

Begin with the load type, the service temperature and the substrates. Epoxy systems give high strength and stiffness with good resistance to heat and chemicals, and one-part versions cure with heat for a controlled, void-free bond line. Polyurethane grades offer toughness and flexibility for dissimilar materials and joints that flex. Two-part products cure at room temperature and suit large assemblies that cannot enter an oven. Gap control, surface preparation, primer use and the difference in thermal expansion between the two materials all affect the finished joint. Where heat must also pass through the bond, thermally conductive grades are available.

Common uses include metal and composite panels, automotive and rail parts, electrical assemblies, appliances and industrial equipment. JOME manufactures structural adhesive in epoxy, polyurethane and other chemistries, including 2K polyurethane structural adhesive and single-component heat-curing epoxy structural adhesive. More grades appear on the Structural Adhesive category page.

JOME supplies Structural Adhesive to wholesalers and distributors with consistent lot quality and application support.
