The rising usage of modified epoxies and polyurethane adhesives, as well as the expanding penetration of methyl methacrylate adhesives, is driving the expansion of the structural adhesives market in wind energy, marine, building & construction, and automotive applications. In the next five years, structural adhesive demand is predicted to rise due to increased composite penetration, desire for non-hazardous, green, and sustainable structural adhesives, and demand for lightweight and low-carbon-emitting automobiles and aeroplanes.
Epoxy is the most often used structural glue because it can stick to many different types of materials, has a high strength, emits less Volatile Organic Compound (VOC) during the curing process, and can withstand severe loads. They are available in both one-component and two-component versions.
