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. Available in 12 Eaches 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 ceramic most plastics and glass to metal Attaching various substrates to masonry and stone Understanding Epoxy AdhesivesEpoxy adhesives including 5 minute 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 adhesives. In general epoxy adhesives have the highest overall strength and offer the best performance and most resistance to high temperatures solvents and outdoor weathering.
