Study Status and Development Trend of Reactive Epoxy Resin Curing Agent
Epoxy resin is thermoplastic pre-polymer with widely applications, it will exhibit outstanding performances after adding curing agent, therefore, the curing agent plays an important role in the application of epoxy resin and the performance of the cured product. Among the curing agents of epoxy resin, the reactive curing agent is convenient to use and has good curing effect and many varieties. The species and reaction mechanism of reactive epoxy resin curing agent are introduced, and some reactive epoxy resin curing agent with excellent performances are reviewed, such as multiple amine curing agent, anhydride curing agent, multiple mercaptan curing agent and imidazole curing agent, etc. And its development trends are pointed out which are environment friendly, high temperature resistant, high strength, good durability, and rapid curing.
