Epoxy resin adhesives are used when high strengths are required, for example, in the automotive and aerospace industries. The structural bondings often replace conventional mechanical connections, enabling cost savings to be made by using lower strength materials or simplified production processes. Epoxides enable highly durable bonding of a diverse range of material combinations.
Curing of the two-part epoxy adhesives generally occurs at room temperature. Higher strengths can be achieved by increasing the temperature during the curing process. With one-part epoxy adhesives, the resin and hardener are already combined in an optimised ratio, thereby simplifying manual use in particular.
Heat must be applied to cure 1K epoxy.
