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 hard epoxy as well as water or solvent based products.
A Stiff Bond for Load Transfer
Combination of several elements with non-moving, stiff joints is important in various projects:
- Precast concrete parts
- Connection of different construction materials
- Application of strengthening systems
- Structural additions such as rails and curbstones
