A hardener—also known as a curing agent or crosslinker—is added to adhesives or coatings to improve their overall performance.
When mixed with the base adhesive, the hardener triggers a chemical reaction (crosslinking) that transforms the material into a tougher, more durable structure.
The main purposes of adding a hardener are:
Enhance bonding strength – provides stronger adhesion, especially under stress
Improve water and chemical resistance – ideal for demanding environments
Increase heat and weather resistance – suitable for outdoor or high-temperature use
Boost long-term durability – reduces aging and degradation over time
Some adhesives are designed to work with or without a hardener, depending on the application. Always follow the recommended mixing ratio and pot life to get the best results.
