Kodak BW400CN negative longevity

[dustmite]

Hello all,
Anyone have any idea how long Kodak BW400CN negatives last before degradation sets in?
Thanks

Hell, How long is a piece of string?

I would say that as it uses the same technology set as C41 colour print film, it would be fairer to compare it to that, than to a traditional B&W film like Tri-X

But there is a difference. With color negs we also have color shifts, all three dyes being different in their rates of degradation.

In C-41 B&W this isn't an issue, of course. As a guess, and it is only that, the negative might fade, but I don't even know if that is the case.

PE?

100 to 120 years. It may lose some density in that time.

Did you make that up or have research/facts to back that up?
