Epoxy structural adhesive is a high-strength engineering adhesive based on epoxy resin, combined with curing agents, toughening agents, fillers, etc. It cures through chemical reaction rather than solvent evaporation, forming a three-dimensional crosslinked network structure after curing. It can achieve excellent bonding for metals, ceramics, glass, wood, and most hard plastics. While withstanding high loads, it also provides sealing, insulation, temperature resistance, and other properties. It is one of the core materials in fields such as aerospace, automotive manufacturing, electronic packaging, and building reinforcement that replace welding and mechanical fastening.
Contact UsThe core advantage of epoxy structural adhesives lies in their ability to provide extremely high tensile shear strength and peel strength after curing, while also offering excellent chemical resistance, electrical insulation, and resistance to fatigue and creep. They exhibit extremely low curing shrinkage and can maintain structural integrity over a wide temperature range (typically -55°C to 150°C or even higher), making them a reliable permanent connection solution capable of load transfer.
