3M™ Structural Adhesive SA9820 is a two-part epoxy adhesive formulated for design flexibility in OEM automotive applications such as structural and chassis assemblies. Excellent for bonding carbon composites, it cures at low temps and delivers the mechanical performance of 1K even on oily metals. Bonded substructures can be stored up to two months before full curing.

    A two-part structural adhesive for design flexibility

    Formulated for long storage and low cure temperatures, our 3M™ Structural Adhesive SA9820 is ideal for bonding dissimilar materials such as carbon fiber and aluminum in automotive OEM structures and substructures. The adhesive cures well below the glass transition temperature at which the resin degrades in many types of composites.

    Room temperature curing for process flexibility

    This two-part epoxy adhesive affords the bond strength of a one-part adhesive. It can be oven cured at temperatures as low as 80°C (176°F) for up to 30 minutes, which allows for carbon fiber and other components to be effectively bonded to metals such as aluminum without distortion or resin degradation. Room temperature curing provides excellent handling performance before cure. This adhesive has a work time of up to 40 minutes and offers flexible geo-fixing options, such as induction, infrared lamp or oven curing.

    An adhesive for production efficiency

    3M™ Structural Adhesive SA9820 allows for bonded substructures to be stored up to two months before full curing – allowing for much greater flexibility during production. The non-sag, non-slump formula delivers excellent gap-filling properties and can be applied either robotically or manually for low-volume or premium higher-volume OEMs. The two-part formula turns orange when properly mixed, creating a clear visual indicator for consistent quality control.
