A collection of various epoxy adhesives that can be used as glues for wood, metal, glass, stone, and some plastics. Epoxy adhesives are a major part of the class of adhesives called "structural adhesives" or "engineering adhesives" (that includes polyurethane, acrylic, cyanoacrylate, and other chemistries.) These high-performance adhesives are used in the construction of aircraft, automobiles, bicycles, boats, golf clubs, skis, snowboards, and other applications where high strength bonds are required. Epoxy adhesives can be made flexible or rigid, transparent or opaque/coloured, fast setting or slow setting. Epoxy adhesives are better in heat and chemical resistance than other common adhesives.
