3M™ Scotch-Weld™ epoxy adhesive 2216 is a flexible, 2-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. 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. We've designed the 3M™ Scotch-Weld™ epoxy adhesive 2216 to perform under extremely frigid temperatures. Because it can withstand temperatures up to -423 deg F (-252 deg C), it is ideal for cryogenic bonding applications. At room temperature it offers a 90 min 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 min (at 200 deg F/93 deg C.) it has a bonded shear strength that can withstand up to 3200 psi at 72 deg F (24 deg C). Epoxy adhesives, including 5 min epoxy, are part of the class of adhesives called \"structural adhesives,\" which include polyurethane, acrylic, cyanoacrylate and others. Epoxies are formulated as liquid reactive polymers that undergo a chemical reaction when mixed and then cure to form a solid plastic 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 needed. This work-life lasts anywhere from a few minutes to several hours. These structural adhesives provide high shear and peel strengths, depending on the formula and better heat and chemical resistance than other common
