3M Scotch-Weld epoxy adhesive 2216 is a flexible, 1-part epoxy adhesive that cures at room temperature. It provides a high strength bond with both high shear and peel strength while remaining highly flexible, making it ideal for applications where vibration and thermal expansion and contraction are common. - 1-part epoxy adhesive also withstands very cold temperatures without overly embrittling. Maintains a strong bond under expansion, contraction and limited movement while retaining good strength after environmental aging.
