Dehumidifying Film Storage - Chemical Interaction

[Erdwolf_TVL]

Good afternoon

 

Will Calcium Chloride affect film? Kodachrome 40 to be precise.

 

I have bought a chemical dehumidifer (normall used to dehumidify rooms and cars) and would like to place this inside a sealed container, along with my supply of film. I will then be placing this unit in the freezer.

 

It would be a bummer if I am doing more harm than good, so please advise!

 

Kind Regards

I would suggest a more inert dessicant like silica gel or Molecular Sieves. Most chemical salts are likely to have an effect on film.

Thanks for that... I'll try to get my hands in some silica gel instead.
