Scotch-Weld™ Part A Non-sag Epoxy Adhesive, Tan, Masonry, Metal, 2:3, >250 deg F, 5 gal

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. 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 to know which half of the product are using.

Features
• Non-sag properties provides greater bond line control than other non-sag epoxies
• 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 helps 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
