ABSTRACT:
The adhesion properties of amine cured epoxy resins are unexpectedly enhanced by addition of a certain combination of high and low molecular weight polyoxyalkylene polyamines. The adhesively superior epoxy resin composition comprises a vicinal polyepoxide, a curing amount of a combination of about 85 wt. % or more of certain polyoxyalkylene polyamines having a molecular weight of less than about 450 and 15 wt. % or less of a polyoxyalkylene polyamine of greater than two primary amine functionality and a molecular weight of about 5,000 and above.
