Bonding, joining and sealing are important to the integrity of your designs. When you’re working with different types of metals, isolation becomes critical. 3M provides a broad range of solutions that help isolate dissimilar metals while allowing you to achieve lightweighting, acoustic and aesthetics requirements. Check them out here.
3M allows designers to incorporate less metal in automotive concepts through the science of sealers and sealer applications. Our melt sealing tapes are formulated to flow when heated in conventional paint ovens, filling broader holes and seams and creating corrosion-preventing seals.
3M delivers structural adhesive liquids that allow for reinforcement and, in many applications, replacement of mechanical fasteners such as rivets and spot welds – ideal for isolation requirements. These liquids can be applied quickly and efficiently and provide flexible working times. They are heat-cured to structural strength at variable rates using established OEM processes – there's usually no need to add process steps for adhesive cure.
Many of our two-part epoxy structural adhesives are available in Duo-Pak cartridge and bulk containers and can be applied with 3M application equipment that allows for precise, consistent mix ratios and minimal product waste.
The power of 3M structural adhesives in a tape format makes for added precision where clean, complete application is critical, such as in BIW areas where corrosion is a main concern. These structural adhesive tapes improve quality by reducing variability of application and can bond to a variety of metal substrates. They also expand during cure to fill gaps, which can help reduce warranty claims in some applications. Structural adhesive tapes are especially useful for bonding long, thin areas where the use of spot welds or mechanical fasteners has traditionally required extra time and labor.
3M is constantly working to meet the evolving challenges of automotive OEM and Tier suppliers worldwide. If you need help finding an existing solution or would like to talk about specific ideas you’re working on, get in touch with us.
