What Is a Structural Adhesive?
Structural adhesive is a type of adhesive specifically designed to support the structural integrity of buildings. It typically consists of epoxy resin, a curing agent, and various additives. The mixing of these components triggers a reaction between the epoxy resin and the curing agent, leading to the hardening of the adhesive and the formation of a strong, durable adhesive film. This film is particularly effective for bonding structural elements, offering high strength and long-lasting durability.
Its common applications include the bonding of steel beams, concrete elements, steel to concrete, fiber-reinforced plastic (FRP), and wood structures. Structural adhesive is characterized by its ability to form secure bonds that can sustain high strength and endure long-term loads. Additionally, it provides excellent resistance to seismic activities and fire, while its application process remains relatively straightforward, making it a crucial component in modern construction and engineering projects.
