A curing agent is a substance that is used to harden a surface or material. It is typically applied to polymer surfaces to facilitate the bonding of the molecular components of the material. The stronger the molecular bonds are, the harder the material surface is.
There are three types of curing agents, namely: curing agents that react with the surface upon which they are applied to facilitate hardening; catalytic agents that do not react with the material surface; and initiator agents that only begin the necessary hardening reactions but do not continue to react with the system.
