There is no universal adhesive in the world. For different materials to be bonded, it is best to use special-purpose adhesives.
If the substrate itself has low strength, there is no need to choose a high-strength product. Otherwise, it will lead to underutilization of resources and increased costs.
Do not only focus on high initial strength; more attention should be paid to good durability.
The performance of adhesives cured at high temperatures is far higher than that of room-temperature curing adhesives. For applications requiring high strength and good durability, high-temperature curing adhesives should be selected.
For α-cyanoacrylate adhesives (e.g., 502 super glue), except for emergency repairs, small-area patching, or continuous production, they are not suitable for materials requiring high bonding strength.
