What are Epoxy Adhesives?
Epoxy adhesives belong to the class of adhesives known as "structural adhesives," which also includes polyurethane, acrylic, cyanoacrylate, and others. These adhesives are formulated as liquid reactive polymers that undergo a chemical reaction when mixed and then cure to form a solid plastic material. The curing process begins once the two parts are mixed in their specified ratio, allowing for 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 offer high shear and peel strengths, depending on the formula, and superior heat and chemical resistance compared to other common adhesives. They are known for their overall strength, excellent performance, and resistance to high temperatures, solvents, and outdoor weathering. These adhesives find wide applications in building and home construction, aircraft and automobile manufacturing, sports equipment assembly, and various other industries. They are favored for their ease of use, mechanical strength, and chemical resistance. Epoxy adhesives can be formulated to be flexible or rigid, transparent or opaque, quick-setting or slow-setting, making them versatile for bonding wood, metal, glass, stone, and various plastics.
Industrial uses for epoxies extend beyond adhesives and include coatings and composite materials such as carbon fiber and glass-reinforced composites. Their ability to flow and conform to the work area, strong adhesion, chemical and heat resistance, and exceptional mechanical and electrical insulating properties make them the preferred choice in these applications.
