ABSTRACT:
The invention has now been made that polychlorinated 1,3- and 1,4-benzene diamines produce cured epoxy resins with better moisture resistance, and higher glass transition temperatures on exposure to high humidity, than known aromatic diamine curing agents. The resulting cured epoxy resins are useful in fibrous composites, structural adhesives and coatings, where high heat distortion and good moisture resistance is desired.
