What are Epoxy Adhesives?
Epoxy adhesives belong to the class of adhesives known as "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) during which the adhesive can be applied and the surfaces positioned as needed. The work life can range from a few minutes to several hours. Epoxy adhesives provide high shear and peel strengths, depending on the formula, and offer better heat and chemical resistance compared to other common adhesives. Overall, epoxy adhesives have the highest strength and provide excellent performance and resistance to high temperatures, solvents, and outdoor weathering.
Epoxy adhesives find wide applications in building and home construction, aircraft and automobile manufacturing, bicycle manufacturing, and various other industries.
