There, I have to respectfully disagree. Floppy disks do not use an
epoxy binder, but usually a polyurethane-based one. (Most are
proprietary formulations). Hard disk coatings usually use an
epoxy-phenolic binder, but they're not on a flexible substrate.
Polyurethane isn't forever and tends to be somewhat hygroscopic.
