What are Epoxy Adhesives?
Epoxy adhesives are part of the class of adhesives called “structural adhesives,” which also includes 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 work life (open 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.
Epoxy adhesives are widely used in building and home construction; aircraft and automobile manufacturing; bicycl
