AbstractAn atmosphere of humid carbon dioxide greatly inhibits the hardening of a liquid epoxy resin cured with diethylenetriamine. Other major components of air, whether dry or moist, do not produce an effect. Because thin films are readily permeated by carbon dioxide and water from the atmosphere, they harden more slowly than do thick films, as is found in practice. Water and carbon dioxide act together producing a network salt of the amine thus blocking its active hydrogen which would otherwise crosslink the resin. The reaction appears to be reversible and in normal air merely slows the crosslinking of thin epoxy films.
