Epoxy resin is widely used as an adhesive due to its strong bonding properties, especially in construction, automotive, and aerospace industries. It adheres well to materials like metal, wood, glass, and ceramics, making it ideal for structural bonding and repairs.

In coatings, epoxy resins provide durable, chemical-resistant, and protective layers on surfaces such as concrete floors, metal pipes, and industrial equipment. These coatings are common in factories, garages, and marine environments where resistance to wear, moisture, and chemicals is essential.

It is also used in electrical and electronic applications, such as encapsulating circuits, insulating components, and protecting sensitive electronics from moisture and vibration.

In composites, epoxy resin is combined with fibers like glass or carbon to produce lightweight, high-strength materials used in aircraft, wind turbine blades, sports equipment, and boat hulls.

Additionally, it serves in tooling and mold-making for prototypes and production parts due to its dimensional stability and ability to capture fine details.
