Curing agents are substances added to materials, such as resins or adhesives, to initiate or accelerate the curing process. They help transform a liquid or semi-liquid state into a solid form through chemical reactions, often involving heat or moisture. Common examples include hardeners used in epoxy systems and catalysts that speed up reactions. These agents play a crucial role in various industries, including construction, automotive, and electronics. By ensuring proper curing, they enhance the performance, durability, and stability of the final product. Proper selection of a curing agent is essential for achieving desired properties in the cured material.
