<p><b>New page</b></p><div>'''Curing (chemistry)'''<br />
<br />
[[Curing (chemistry)]] is a chemical process employed in [[polymer chemistry]] and [[process engineering]] that produces the toughening or hardening of a [[polymer]] material by cross-linking of polymer chains. This is brought about by chemical additives, ultraviolet radiation, electron beam or heat.<br />
<br />
== Process ==<br />
<br />
Curing can be initiated by heat, humidity, radiation, electron beams, or chemical additives. The process involves the formation of long-chain [[molecular structure|polymer chains]]. These polymers are then cross-linked to create a three-dimensional network of connected molecules. The resulting material is resistant to deformation and has improved physical properties.<br />
<br />
== Applications ==<br />
<br />
Curing processes are widely used in the production of [[composite materials]], [[adhesive]]s, [[paint]]s, [[varnish]]es, and [[rubber]]. In the case of thermosetting polymers, curing is an irreversible process as it sets the polymer into a solid shape that cannot be re-melted or reformed.<br />
<br />
== Curing Agents ==<br />
<br />
[[Curing agents]] are substances that promote or control the curing process by taking part in it. The choice of curing agent can significantly affect the physical properties of the cured polymer, the curing rate, and the nature of the chemical reactions that take place.<br />
