A structural adhesive bonds substrates together and is made from two or more parts that have been bonded together using an adhesive with higher structural strength.

When an adhesive is applied in liquid form, it wets the substrate and is partly absorbed by it. It then transforms into a solid, bonding the substrates together in a process known as “curing.”
The bond does not break when external forces are applied to it. Together, the bond’s strength, the structural adhesive, and the substrate’s strength determine the structure’s overall strength.
The curing system of the structural adhesives varies according to the substrates used, application, and chemistry, among other factors. Structural adhesives can be heat-cured, chemically cured, UV-cured, moisture-cured, or pressure-sensitive.
