Thermosetting Resin - an overview ScienceDirect Topics

In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. Heat is not necessarily applied externally, but is often generated by the reaction of the resin with a curi… Webb1 aug. 2006 · Thermoset composite materials are used in a wide range of applications in industries such as automotive and construction.
