Abstract:
     In this invention, the organic compounds of lanthanum, cerium, praseodymium and neodymium are used as hot curing promoter of bisphenol-A type epoxy resin. They exert promoting action on all curing agent systems, prompting hot curing speed and reducing stoving time by 25~50%. The original properties of the cured resin can be well preserved. Among them, the organic compounds of praseodymium and neodymium can further improve the properties of the cured resin.
