hardeners
Catalysts for curing
Hardeners are substances that cause other materials to become hard or rigid.
In construction and manufacturing, hardeners are added to epoxies, resins, or concrete to accelerate curing and increase durability: Mix the epoxy with its hardener before applying.
In metallurgy, hardeners are alloying elements that increase a metal's hardness.
