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 liquid reactive polymers that undergo a chemical reaction when mixed and cure to form a solid plastic material. Once the two parts are mixed in the specified ratio, they begin the curing process, providing a limited work life during which the adhesive can be applied and the surfaces positioned as needed. This 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 widely used in various industries, including building and home construction, aircraft and automobile manufacturing, sports equipment assembly, and many other applications. Epoxy adhesives are favored for their ease of use, mechanical strength, and chemical resistance. They 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 like 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.
