For uncrosslinked Epoy resin try Dimethylformamid as a solvent at room temperatur,

for crosslinked Epoxy resin use hot DMF at about 60 to80 °C for a few hours (you have to experiment)

Please watch the safty regulations if handling with DMF.

Methylethylketone (MEK, butan-2-one, CH3-C(O)-CH2-CH3) is also a reasonable solvent for epoxy resins.

Similarly, MIBK (Methyl isobutyl ketone, 4-Methylpentan-2-one) is worth a shot.

As above, have a look at the MSDS - both are flammable solvents and I can't remember their toxicity information.

Thank you so much. It was very useful.
