Soybean oil–based Curing Agents for Epoxy resin

Two novel soybean oil–based curing agents were synthesized by Chinese researchers in order to increase the flexibility properties of conventional epoxy resin. The curing agents were obtained from  the reaction between epoxy soybean oil and ethylene diamine (EEDA) and epoxy soybean oil and isophorone diamine (EIPDA). Mechanical tests and Shore D hardness tests suggested that excessive EEDA greatly enhanced the toughness of cured products because of the introduction of aliphatic chains.
