Rigid bonding is a traditional bonding method where adhesive is applied to the surface of substrates that are then pressed together, and after time the two objects are strong and rigidly fixed. The adhesive layer between the objects is thin and hard. Load, stress, and movement are transferred directly. Rigid bonding is recommended when bonding very similar materials that are not subjected to cyclic stress. Typical rigid adhesives are water or solvent-borne as well as hard epoxy adhesives.
