Highlights
  • 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

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.

Our 3M™ Scotch-Weld™ Epoxy Adhesive 2216 is designed for applications where high performance and flexible bonds are required. Its flexibility makes it ideal for applications involving dissimilar surfaces and where differing coefficients of thermal expansion are a consideration. Once fully cured, the epoxy maintains an extremely strong bond under expansion, contraction, and limited movement while also maintaining a good retention of strength over time and after environmental aging. With a 2:3 mix ratio it is a low viscosity epoxy. It flows smoothly for accurate dispensing. Both the base and accelerator are coded in contrasting colours to ensure you know which half of the product you are using. We've designed 3M™ Scotch-Weld™ Epoxy Adhesive 2216 to perform under extremely frigid temperatures. Because it can withstand temperatures up to -423°F (-252°C), it is ideal for cryogenic bonding applications. At room temperature it offers a 90-minute work life to allow for repositioning and adjustments. It will slowly cure over 7 days, but can be heat cured to reduce this to as little as 30 minutes (at 200°F/93°C.) It has a bonded shear strength that can withstand up to 3,200 psi at 72°F (24°C).

Suggested applications
  • Designed for general industrial, sporting goods, solar energy, wind energy, composites, electronics, military, transportation, and aerospace applications
  • Ideal for panel & trim bonding, gluing, joining, attaching, assembling, applications
  • Alternative to riveting or welding, bolt setting, frame building, rivet-free assembly
