WebIn order to study its effect for curing unsaturated polyester resin (UPR) composites containing calcium carbonate (CaCO3) ﬁller, this paper ﬁrst investigated the inﬂuence of microwave power and microwave irradiation time on the curing characteristics of UPR. WebChain propagation. Mixing such a resin system is fast and straightforward, and it is all about adding a curing initiator to a resin solution. The curing initiators do not take part in the chemical reaction but only activates the process. Two fundamental steps are vital to the understanding of this curing mechanism: Initiation and chain-growth.
