Triethylenetetramine ( TETA )


The reactivity and uses of TETA are similar to those for the related polyamines ethylenediamine and diethylenetriamine. It is primarily used as a crosslinker (“hardener”) in epoxy curing.  TETA, like other aliphatic amines, react quicker and at lower temperatures than aromatic amines due to less negative steric effects since the linear nature of the molecule provides it the ability to rotate and twist.
