<p>N-Alkyl-N'-aryl-p-phenylenediamines, when added at 2.5 to 12.5 % by weight, based on the total weight of the epoxy resin and hardener, cause the epoxy resin after curing to exhibit substantial increases in physical properties, such as strength, stiffness, toughness and hot/wet properties, compared to the properties of the cured, but unmodified epoxy resin.</p> |
