3M™ Scotch-Weld Epoxy Adhesive 2216NS is a flexible, non-sag, 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.

When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.

Non-Sag Properties Provides Greater Bond Line Control
3M™ Scotch-Weld Epoxy Adhesive 2216NS is a non-sag version of our 3M™ Scotch-Weld Epoxy Adhesive 2216. It 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 colors to ensure you know which half of the product you are using.

Recommended Applications


Hard disk drive component assembly
Potting where expansion and thermal changes may occur, such as solar panels and other construction applications
Military bonding applications, for example bonding parts on movable transports
Bonding ceramic, most plastics and glass to metal
Attaching various substrates to masonry and stone
Excellent for Cryogenic Bonding Applications


Our 3M™ Scotch-Weld Epoxy Adhesive 2216NS is designed 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.
