Epoxy is a thermosetting adhesive. It is produced by polymerizing the mixture of two starting compounds, resin ad hardener. After mixing resin with a specified catalyst, curing starts. The curing involves the reaction of molecular chains at chemically active sites, which causes an exothermic reaction. The covalent bonds between resin’s epoxide groups and catalyst’s amine groups produced by the combination allow cross-linkage of polymer, and hence dictate the strength and rigidity of the epoxy.
The electrical, chemical, and thermal resistance of the epoxy adhesives can be altered by monitoring curing conditions by choice of resins, hardener compounds, and temperature. Therefore, epoxy adhesives are developed for a wide range of applications and operating conditions. These adhesives adhere to a range of materials and their properties that rely on the specific chemistry of the system and cross-linking nature. Epoxy adhesives can tolerate extreme weather conditions and stress. It joins a wide range of surfaces together with a permanent, strong, and robust bond.
In 2021, the epoxy adhesive market contributes $8,217.9 million, and it is projected to reach $13,483.9 million in 2030, advancing at a rate of 5.7% in the near future. It is attributed to the rising demand for adhesives for various industrial activities such as automotive, plastic, woodwork, manufacturing, and marine industries.
Under the end user segment, the building & construction sector holds the largest revenue share of the epoxy adhesive industry, amounting to $2.3 billion revenue in 2021. It is ascribed to the versatility of adhesives in building and construction applications. These adhesives are utilized for surface repairing, laminating, and filling gaps, as well as they are effective on cellular PVC, plywood, wood, metal, water-resistant tile, ceramics & porcelain, gypsum & drywall, fiberglass, and bricks.
Therefore, the industrial applications of the epoxy adhesives, led by their strong and rigid bond leads to their huge demand and hence drive sales
