The designs you’re thinking of often depend on subtle curves and contours. They must also be functional. Achieving both at once presents real challenges. Especially when your body-in-white designs could incorporate dozens of sensors and cameras, and sit on electrified powertrains. At 3M, we deliver technologically advanced abrasives, structural adhesives, engineered damping materials and flexible sealants, to name a few, to help move your design out of your head and onto the production line. That’s what we’re doing today. Tell us what you’re thinking about tomorrow. We’re happy to help.
As 3M actively works to develop new technologies and combine existing ones, we are continually discovering solutions that solve more than one challenge at a time. That’s why we can meet the needs of automotive OEM professionals and Tier suppliers wherever they are in the automotive body-in-white process, from design to simulation to assembly.
Our structural adhesive liquids and tapes are available in epoxy, acrylic and urethane chemistries. That means you can add structural strength to a broad range of areas and applications. Explore them here.
Our structural adhesives are suitable for bonding primary structures and for hang-on parts like doors, tailgates, hoods and trunk lids. Epoxy and acrylic adhesives are formulated for high-strength steel and aluminium, which makes them excellent for hem bonding. Many of them cure at lower temperatures (room temperature to induction curing at temperatures as low as 80°C), so you can use them for bonding composites such as carbon fibre reinforced polymers without distortion or resin degradation. Plus, bonded substructures can be stored for weeks and even months after induction.
3M structural adhesive tapes are ideal for electrical isolation, allowing for the use of mixed materials without additional e-coat. They can be applied without pumping, dosing or squeeze-out, and they are compatible with most draw and lube oils.

3M epoxy and acrylic structural adhesives can be used in conjuction with – or even in place of – mechanical fasteners for chassis components. They provide consistent wet-out across uneven surfaces, making them ideal for reinforcement of metal stamped parts during the assembly of the body to the chassis.
Featuring extremely flexible work times, shear strengths and peel strengths, our structural epoxies provide excellent heat and chemical resistance, as well as resistance to solvents and weathering.

Powertrain – ICE Solutions
3M urethane structural adhesives combine structural strength and mechanical flexibility to keep individual EV battery cells stable and aligned. Our heat-cured epoxies and acrylics are excellent for bonding module panels and battery pack cases without the need for primers.

Our selection of structural tapes provides solutions for what you need the most in exterior and glass assembly: bonding, sealing, and isolation. In fact, our 3M™ Structural Adhesive Tapes are designed to expand during cure to accomplish all three.
You can also add efficiency to this list. Our 3M™ Structural Bonding Tapes are pre-designed and pre-applied to hardware including rear view mirror components, sensor brackets and mounting pins. All of our structural bonding tapes feature adhesive designed to bond quickly to glass without added fixturing and heat-cures during standard autoclave processes. Or, it can be activated with UV light and applied post-autoclave Our 3M™ Structural Bonding Tape 9550 with Light Activated Adhesive eliminates the fixturing, priming, metering, pumping, purging and heating required with polyurethane processes.

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.
This structural adhesive does far more than just help bond substrates. 3M™ Structural Adhesive Tape SAT1010 allows technicians to apply adhesive in precise locations with consistent thicknesses, ideal as an alternative to clinch flange adhesion and for preventing galvanic corrosion. Learn more about how this solution can save time and increase efficiency in OEM manufacturing processes.
