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 overly embrittling.
Easy Application, Flexible Performance 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 colors to ensure you know which half of the product you are using. Recommended 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 most plastics Bonding ceramic, plastic and glass to metal Attaching various substrates to masonry and stone Reliable, Long-Term Dependability We've designed the 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. Structurally Sound Epoxy adhesives are part of the class of adhesives called "structural adhesives," which also includes polyurethane, acrylic, cyanoacrylate, and others. Two part structural adhesives are formulated as liquid reactive polymers that undergo a reaction when mixed, and then cure to form a solid material. Once the two parts are mixed in their specified ratio, they begin the curing process and offer a limited working time where the adhesive can be applied and the two surfaces positioned as required. This "work life" lasts anywhere from a few minutes to 48 hours or longer. This class of structural adhesives provides high shear and peel strengths, depending on the formula and better heat and chemical resistance than other common adhesives. Epoxies that are heat cured are more heat and chemical resistant than those that cure at room temperature. Epoxy adhesives are widely used virtually anywhere high-strength bonds are needed along with resistance to environmental conditions. These adhesives are popular for their ease of use, mechanical strength, and chemical resistance. Formulations can be created to make epoxies that are flexible or rigid, transparent or opaque, quick setting or slow setting. The versatility with which epoxy adhesives can be formulated helps meet almost any requirement for bonding wood, metal, glass, stone, and various plastics. Note: 3M™ Scotch-Weld epoxy adhesive 2216 B/A is identical to 3M™ Scotch-Weld™ Epoxy Adhesive EC-2216 B/A in chemical composition. 3M™ Scotch-Weld™ Epoxy Adhesive EC-2216 B/A has been labeled, packaged, tested, and certified for aircraft and aerospace applications. 3M™ Scotch-Weld™ Epoxy Adhesive 2216 B/A may be used for aircraft and aerospace applications if proper Certificates of Test have been issued and material meets all aircraft manufacturer’s specification requirements.
