Epoxy Structural Adhesives

Strong chemistry for durable bonds

For high-strength durable bonds that resist high temperatures, solvents and outdoor weathering, 3M’s one- and two-part epoxy adhesives have decades of proven performance. By eliminating the need for mechanical fasteners, our durable epoxies improve impact resistance and fatigue performance. They also provide high shear and peel strengths, making them ideal for general industrial, sporting goods, transportation, appliance, electronics and military applications.

Flexible enough for your most innovative designs

3M™ Scotch-Weld™ Structural Epoxy Adhesives are available in a variety of formulations – flexible or toughened, transparent or opaque, quick- or slow-setting – to meet almost any requirement for bonding metal, glass, stone, plastics and wood.

Our two-part epoxy adhesive also offers a work life (open time) that lasts anywhere from a few minutes to several hours for precise positioning.

Our one-part heat-curing epoxy adhesives are convenient, reduce waste and have a virtually unlimited work life until heat-cured. They are ideal for metal-to-metal bonding, providing exceptional strength without the need to mix, meter and weigh components.
