Strength for how you work.

Structural adhesives can do much more than provide strength to automotive bonds. They can help you hit your targets for lightweighting, corrosion protection, crash safety and more. You can use structural adhesives in conjunction with mechanical fasteners and, in many cases, you can replace them. They can also save you significant time and money during production by enabling mixed materials, reducing panel fatigue and resin degradation, filling gaps, managing NVH, and reducing process steps. 3M™ Structural Adhesives are available in varying chemistries and formats so you can use them in multiple areas of the vehicle. Our experts are happy to help you determine the right structural adhesive solution for your specific needs, including automated application.

    3M™ Structural Bonding Tape 9550 with Light Activated Adhesive

    Featuring a pressure-sensitive adhesive that activates through exposure to ultraviolet light, this structural tape is formulated for bonding hardware components such as rearview mirror buttons, sensor brackets and mounting pins to glass post-autoclave. Adhesive eliminates the fixturing, priming, metering, pumping, purging and heating required with polyurethane processes. Tape is pre-applied to components with multiple packaging options.

  • 3M™ Structural Adhesives Tape SAT1010

    3M Structural Adhesive Tape SAT1010 is typically used for body-in-white applications from paint-pretreatment through e-coat. This tape is heat-cured in a standard e-coat oven to help reduce process steps. It is designed to provide structural bonding strength for metal bonding and isolation of dissimilar materials. It expands during cure to fill gaps for excellent resistance to galvanic corrosion. SAT1010 is easily die-cut.

  • 3M™ Structural Adhesives SA9816

    This two-part epoxy adhesive is formulated for steel or aluminum hem flange bonding in body-in-white. It cures during e-coat bake to minimize panel distortion or resin degradation on composites. It can be induction pre-cured to prevent parts from moving during transport or during the e-coat bath, which can help increase design flexibility and reduce cycle time. Non-sag adhesive can be applied either robotically or manually.

    Designed to be cut to weight quickly and precisely, our lead-free composite 3M wheel weight material helps reduce inventory and potential rejects. Levelwound rolls work with Esys Automation's AutoW8t System to enable automated cutting and assembly, which can dramatically improve speed, quality and cost of tire balancing.

  • 3M™ Melt Sealing Tapes (PDF, 143.57 KB)

    These tapes bond and seal automotive panels before paint application without additional process steps. Repositionable thermoset tapes apply easily into roof ditches, combined panel edge seals and holes. The tape material softens and flows during heat curing to cover surface imperfections and forms a smooth, paint-receptive surface.

  • 3M™ Thread Sealants and Fastener Adhesives

    3M offers sealants and adhesives pre-applied to threaded fasteners to help reinforce seals to critical areas such as engine compartments. Fluid-, temperature- and pressure-resistant sealants do not harden, allowing for part replacement. Microencapsulated epoxy adhesives activate and cure upon assembly to save process steps.
