Faster and easier with premium bonding strength

  • When your project requires reliable long-term bonding of dissimilar substrates, 3M™ Scotch-Weld™ Structural Acrylic Adhesives significantly improve throughput and productivity. These adhesives can withstand extreme temperatures, build strength rapidly and resist impact and peel.

    Created for designers, engineers and manufacturers who need efficient bonding and greater design flexibility, 3M™ Scotch-Weld™ Structural Acrylic Adhesives are suitable for bonding most plastics, aluminum, steel, oily metal surfaces. Fast and easy to apply, our acrylic adhesives provide bonds that replace metal fasteners for both static and dynamic loads and enable improved aesthetics.

    3M™ Scotch-Weld™ Structural Acrylic Adhesives also offer low-odor and non-flammable formulations to help where odors can be annoying or where flammability is a concern.

Which adhesives are right for you?

These questions can help narrow down your adhesive choices.

  • What materials will be bonded?
    Structural adhesives work by adhering to the top surface of the bonded parts, so it’s important to know the exact material and condition on those surfaces. For metals, will the adhesive be applied to bare metal, or will there be a paint or coating on the surface? For plastics, exactly which base resin? Could there be residual release agents on the surfaces used for mold release?
  • What is the preferred cure speed?
    The chosen structural adhesive must have enough work life (open time, pot life) to allow proper mixing and application of the adhesive and assembling of the bonded parts. Smaller assemblies or shorter cycle time production processes may be able to use a faster curing adhesive with a work life of only five minutes or less, while larger assemblies that require alignment and clamping will probably need a work life of 20 minutes or more.
  • What surface preparation will be required?
    Structural adhesives generally prefer clean, rough, dry surfaces for highest bond strength. This typically means either light abrasion and solvent cleaning of the surface, or solvent cleaning followed by chemical etching or applying a primer. Adhesion tests should be performed to determine the adequate surface preparation for a specific application.
  • What type of joints are best for structural adhesives?
    Joint designs that put the adhesive bond under shear, tension, or compression forces will provide the highest strength. Designs that tend to apply peel or cleavage forces to the adhesive, where the applied stresses are not distributed over the entire bond area, will have lower bond strength, but the bond may still be sufficient for the needs of the application. In addition, optimum bond line thickness typically ranges from 0.005" to 0.020". The adhesive qualification process should always include testing of prototype assemblies to ensure the adhesive will provide enough performance.
  • How are structural adhesives used and applied?
    Structural adhesives come in many forms, including low viscosity liquids and non-sag pastes, one- and two-component formulations, short and long work lives, and various package sizes and shapes. Most two-part structural adhesives are available in both bulk containers and convenient, easy-to-use cartridge mixing systems.
  • What are the general characteristics of the different types of structural adhesives?
    All structural adhesives provide at least 1,000 psi of overlap shear strength to aluminum, but the different adhesive chemistries have various properties:
