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. Once the two parts are mixed in their specified ratio, they begin the curing process and offer a limited working time for application and positioning of surfaces. This work life can range from a few minutes to several hours.
Epoxy adhesives provide high shear and peel strengths, depending on the formula, and exhibit better 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.
Epoxy adhesives find extensive use in building and home construction, aircraft and automobile manufacturing, assembly of bicycles, boats, golf clubs, skis, and snowboards, as well as various home use and other applications. They are preferred in applications where high-strength bonds and resistance to environmental conditions are required. These adhesives are popular for their ease of use, mechanical strength, and chemical resistance. The versatility of epoxy adhesives allows for the formulation of flexible or rigid, transparent or opaque, quick-setting or slow-setting adhesives. This adaptability enables bonding of wood, metal, glass, stone, and various plastics to meet diverse requirements.
