If I let it cure properly (up to couple of days depending on whether
the environment is sealed or not) it holds just fine as gasket. On
prolonged use in contact with hot high ABV alcohol it might separate
from the copper. I believe Harry has found some other alternatives you
might try if that's a problem. You can use it for boiler gaskets and
even for glueing on capillary joints if necessary. No off-flavors
detected in some ten years of use.
