3M™ Scotch-Weld™ Epoxy Adhesive 2216 is a flexible, two-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. It also withstands very cold temperatures without becoming brittle.
Key Features
Very flexible bond is resistant to extreme shock, vibration and flexing, making it ideal for potting and applications in the transportation industries
Maintains a strong bond under expansion, contraction, and limited movement while retaining good strength after environmental aging
Excellent for cryogenic bonding applications or adhering substrates that will be exposed to extreme cold
Medium viscosity help minimize running, dripping, or migration while also self-leveling
Versatile bonding agent will adhered a wide variety of similar and dissimilar substrates, including metals and masonry
Can be heat cured to reduce curing times from 7 days to as a little as 30 minutes
Applications
Cryogenic bonding applications where bonded agents might experience temperature extremes
Potting where expansion and thermal changes may occur, such as solar panels and appliance or construction applications
Military bonding applications, for example bonding parts on movable transports
General aerospace and transportation bonding where vibrations and movement are common
Bonding ceramic, most plastics and glass to metal
Attaching various substrates to masonry and stone
