In order to obtain a low-toxic and environmentally friendly epoxy system, the novel green curing agent L-Triptophan was used, in combination with the two commercial late curing agents 2-Undecyl-1H-imidazole and 3,3'-(4-Methyl-1,3-phenylene)bis(1,1-dimethylurea), as hardener system for the cross-link of Diglycidyl Ether of Bisphenol A (DGEBA). The thermal behavior of the precursors mixtures was evaluated by dynamic and isothermal Differential Scanning Calorimetry (DSC) and confirmed L-Tryptophan as a possible novel green curing agent for DGEBA. These encouraging results pave the way for a further study of a new class of low-toxic and sustainable curing agent systems for the production of fully bio-based epoxy resins.

Abstract

In order to obtain a low-toxic and environmentally friendly epoxy system, the novel green curing agent L-Triptophan was used, in combination with the two commercial late curing agents 2-Undecyl-1H-imidazole and 3,3'-(4-Methyl-1,3-phenylene)bis(1,1-dimethylurea), as hardener system for the cross-link of Diglycidyl Ether of Bisphenol A (DGEBA). The thermal behavior of the precursors mixtures was evaluated by dynamic and isothermal Differential Scanning Calorimetry (DSC) and confirmed L-Tryptophan as a possible novel green curing agent for DGEBA. These encouraging results pave the way for a further study of a new class of low-toxic and sustainable curing agent systems for the production of fully bio-based epoxy resins.
