offers Bakelite epoxy curing agents, which include Naminoethyl piperazine, diethylenetriamine, triethylenetetramine and tetraethylenepentamine.
Bakelite epoxy curing agents include Naminoethyl piperazine, diethylenetriamine, triethylenetetramine and tetraethylenepentamine.
The formulations were based on the diglycidyl ether oligomer of bisphenol-A (DGEBA) DER 331, produced and sold by Dow Chemical of Brazil SA, and the three aliphatic comonomers triethylenetetramine (TETA), tetraethylenepentamine (TEPA) and 0,0 bis (2-aminopropyl propylene glycol) (Jeffamine D230), supplied by Fluka SA.
The complex is to produce ethylenediamine, diethylenetriamine, triethylenetetramine and higher molecular versions.
In addition, there are few studies about used other amines such as ethanolamine (18) and triethylenetetramine (22).
In this functionalization process, grafting triethylenetetramine (TETA) on the MWCNT surface can bridge the connection of MWCNTs to the epoxy matrix.
2] in AP is lower than common aliphatic polyamine, such as ethanolamine, ethylenediamine, diethylenetriamine, and triethylenetetramine, etc.
3] calculated the activation energy of DGEBA cured with triethylenetetramine from the gel time method as 53-71 kJ/mol and Cadenato et al.
The residual black solid was then dried in a vacuum oven at room temperature followed by the reaction with 120 ml triethylenetetramine (TETA, supplied by Shanghai Chemical Reagent Company, People's Republic of China) at 120[degrees]C for 96 h.
The gained solid reacted with excess triethylenetetramine (TETA, 120 ml) at 120[degrees]C for 96 hr.
