Definition of curing agent


The curing agent for unsaturated polyester resin is a kind of peroxide, also called initiator or catalyst, which can trigger the crosslinking of resin under the action of accelerant or other external conditions.The "catalyst" is different from the traditional "catalyst".Traditionally, the term "catalyst" has been used to refer to reactants that promote the reaction without themselves being consumed.However, in the UPR curing reaction, the peroxide must change its own structure before it can "catalyze" the reaction. Therefore, a more appropriate name for the peroxide used for the UPR curing should be "initiator" or "initiator".When it comes to peroxides the two concepts that we need to understand are reactive oxygen content and critical temperature."Reactive oxygen" or "reactive oxygen content" is a concept closely related to curing agent and often misunderstood.
