3M Structural Solutions for Automotive OEM
Structural adhesive liquid and tape solutions for automated, semi-automated or manual application
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.

Structural Adhesives for Body-in-White Applications
Strengthen bondlines and simplify the manufacturing process. Structural adhesives from 3M are designed to help automotive OEMs enhance or even replace welds, nuts, bolts and other mechanical fasteners used in BIW applications. They enhance multi-material bonding capabilities – aluminum, structural steel and lightweight composites to name a few – and are suitable for bonding primary structures and hang-on parts like doors, tailgates and hoods. They are two-part adhesives that cure at room temperature, helping OEMs reduce energy and emissions throughout the BIW assembly process. By increasing stiffness and enabling more robust bondlines, they also help mitigate NVH.

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.
-
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.
