Keith, I agree it's asking epoxy to do something it was never designed to do, but since no money is riding on this discussion let's pursue it a bit for kicks and giggles.
Belzona 1511 will withstand a sustained temp of up to 392 degrees Fahrenheit. Even though the flame and gases reach much higher temps, it is only for a microsecond. That's the reason it takes repeated shots in a short time to heat up the metal.
Is it possible that the epoxy would never reach 392 itself?
And, is it not also true that the heat shielding tiles are held on the space shuttle with epoxy. They get glowing red on reentry.
Stan,
Ablative tile keeps the heat from transferring to the shuttle, it glows red in one side and can be touched on the other. Yes, glued in place.
The problem I see is you are going to have different expansion rates between steel and epoxy. That would be the end of the epoxy, along with the heat itself.
The differing expansion rate between materials is probably why nobody has successfully developed a plating process to restore old barrels.
Best,
Ted
