The Strong Complement to Welding, Rivets and Mechanical Fasteners

  • The better way to stronger production possibilities.

    When you need advanced strength and durability along with the improved aesthetics of smooth, invisible bond lines, look to 3M™ Scotch-Weld™ Structural Adhesives. From kitchen appliances and sporting goods to automobiles and aerospace, our wide variety of structural adhesives includes options to meet your design and manufacturing needs. Whatever your design, engineering or production requirements, look to 3M for solutions.

    Our broad product portfolio encompasses different chemistries, curing methods, open times and final bond capabilities, including low-odor and non-flammable versions of certain chemistries to meet specific regulatory and safety stipulations. We also have a world-class team of experts who can work with you to address specific design or process requirements such as lightweighting or productivity and answer the question: How can you make your product better?

Core Benefits of Structural Adhesives

Each adhesive is unique, but adhesive families tend to share certain characteristics for which they perform well. These are the key characteristics described in the chemistry families below.

  • Strength

  • Material Bonding

  • Process Efficiency

  • Impact Resistance

  • Lightweighting

  • Innovation in Design

  • Aesthetics

  • Water Intrusion

  • NVH

Structural Adhesive Chemistries

  • These two-part adhesives offer great strength and design flexibility.

  • These adhesives provide excellent durability and resistance to environmental extremes.

    One-Part Epoxy

    Two-Part Epoxy

  • These one-part products combine the speed of hot melt adhesives with the structural benefits of moisture-curing chemistries.

  • These formulations are ideal for creating strong, flexible bonds between dissimilar materials.

  • These adhesives provide tight fits and seals in threadlocking, pipe sealing and related applications.

  • These products reach handling strength in 5-10 seconds and achieve extremely high tensile strengths.
