WebGlycidylamine Epoxy Resins These epoxy resins have relatively high levels of functionality and are formed as a result of the contact reaction between aromatic amines and epichlorohydrin. Industrial grades include triglycidyl-p-aminophenol (functionality 3) and N,N,N′,N′-tetraglycidyl-bis-(4-aminophenyl)-methane (functionality 4). http://blog.plastics-technology.com/epoxy-manufacturing-process-applications/
Epoxy resins made of (long-chain) polyols are also added to improve tensile strength and impact strength. A related class is cycloaliphatic epoxy resin, which contains one or more cycloaliphatic rings in the molecule (e.g. 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexane carboxylate).
