1. An aliphatic epoxy resin precursor composition comprising:
an epoxy resin precursor comprising a pre-cured, at least partially reacted, but not completely polymerized or cured, mixture of (i) an epoxy component comprising a glycerol glycidyl ether and (ii) a reactive component comprising 1-amino-3-aminomethyl-3,5,5-trimethylcyclohexane (isophorone diamine or IPD), the mixture containing free epoxide groups;
wherein:
the precursor composition contains no bisphenol-based epoxy resins;
the precursor composition contains greater than about 60% (w/w) of the epoxy component in reacted and unreacted forms combined and relative to the precursor composition; and
the precursor composition contains between 1% and 10% (w/w) of the reactive component in reacted and unreacted forms combined and relative to the precursor composition.
