KODAK HIE expired, Frozen, Usable?
I have a chance on buying some Kodak HIE that expired in 2001 but has been frozen since purchase. Any opinions if it would still be usable? I know I have worked with expired film in the past without issues that was frozen but not infrared.
Hie does not last long after the experation date and i wouldnt buy it unless its a dirt cheap deal.
I have recently used HIE 3 years out of date that had been kept in the fridge and was happy with the results. It is always a risk especially if you are shooting something important to you or a client. It come down to the amount of money that you are willing to risk on your investment. Could you buy a few rolls to check it out? I bracketed mine at 400/640/1020 asa and developed it at 1+1 for 13 mins in ID11. All negs are printable. I use a red filter and metered through the camera. Good luck.
Yes, it should be usable.
Yes I think it should be usable if frozen when purchased (and purchased when fresh - i.e. not expired).

w.r.t. the longevity of frozen and properly stored HIE, nobody has ever provided documented or traceable evidence to the contrary of my informed guesstimate of 10-15 years (either posted to APUG or elsewhere that I have searched).
