Curing 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. Even if it is strongly associated with the production of thermosetting polymers, the term "curing" can be used for all … See more During the curing process, single monomers and oligomers, mixed with or without a curing agent, react to form a tridimensional polymeric network. In the very first part of the reaction branches of molecules with … See more In the case of concrete, curing entails the formation of silicate crosslinks. The process is not induced by additives. In many cases, the … See more • Vulcanization • Cross-link See more Epoxy resins are typically cured by the use of additives, often called hardeners. Polyamines are often used. The amine groups ring-open the epoxide rings. In See more Cure monitoring is, for example, an essential component for the control of the manufacturing process of composite materials. The material, initially liquid, at the end of the process will be solid: viscosity is the most important property that changes during … See more WebOptical polymer curing. FDTD. This page provides a simple example that describes how to simulate a polymer curing process where the refractive index of the polymer changes as a beam propagates through it. As light propagates through the polymer, a small fraction of power is absorbed, which changes the refractive index.
