A chemically resistant epoxy resin composition comprising a vicinal polyepoxide, an aromatic polyamine and a condensation product of a polyoxyalkylenediamine of about 400 molecular weight or below with at least 2 moles of maleic anhydride.
An epoxy resin composition comprising a vicinal polyepoxide, an aromatic polyamine which is the condensation product of aniline and formaldehyde and a condensation product of a polyoxyalkylenediamine of the formula
- H.sub.2 NCH(CH.sub.3)CH.sub.2 --OCH.sub.2 CH(CH.sub.3)--.sub.x NH.sub.2
- wherein x is about 5.6 or 2.6 with maleic anhydride.
A method for making a solvent resistant epoxy resin composition which comprises combining a vicinal polyepoxide, an aromatic polyamine and a condensation product of a polyoxyalkylenediamine of about 400 molecular weight or below with at least 2 moles of maleic anhydride and allowing the mixture to cure.
A method for making a solvent resistant epoxy resin composition comprising mixing together a vicinal polyepoxide, an aromatic polyamine which is a condensation product of aniline and formaldehyde and a condensation product of a polyoxyalkylenediamine of the formula
- H.sub.2 NCH(CH.sub.3)CH.sub.2 --OCH.sub.2 CH(CH.sub.3)--.sub.x NH.sub.2
- wherein x is about 5.6 or 2.6 with maleic anhydride and allowing the mixture to cure.
