Research Progress in Unsaturated Polyester Resin Room-temperature Curing System

In this paper,the species composition and characteristics of the initiator and accelerant in the redox initiation system which was used for the unsaturated polyester resin cured at room temperature were summarized. The progress of UPR curing at room temperature and its reaction kinetics in recent years were reviewed. And the purpose is to make people to have knowledge and understanding to room temperature curing system and its application.
