I am not a beer person, so I didn’t know it had another meaning lol.For those whose minds default to beer, "IPA" here is most likely Isopropyl Alcohol.
Might try it on a test roll just to see what happens.@MCB18 there won't be much, if any, of an effect at all. Give it a try.
I’m thinking about trying to de-remjet some cine film (250D and 50D), and the most annoying part is definitely drying. I have heard that IPA is a good drying agent, and will help speed up drying immensely. but I’m wondering how much it would affect the emulsion. Anyone have any thoughts on this?
I use 100% iso as a finishing stage for Antihalation Layer removal of Aviphot films.
No damage to report either to the emulsion or PET base.
I use it as 10-20% additive for my rinse aid that I use for ~10 films before discarding. No problems to report, just speedy drying.

Haven't done measurements, but gut feeling says thay the drying time is almost halved. With 100% iso we're talking up to ~5 minutes, with 20% about an hour? The more you add, the more expensive it gets, the quicker the drying. Could run an experiment.How long does it take to dry like this with 10-20% alcohol?
For juicy halation to appear, one needs to 1) remove layers that protect against this, 2) expose film with layers removed, 3) develop ASAP to avoid fogging. For extra juicy effect, one can even put a white/gray paper on the film pressure plate for extra blooming...Why do you want to remove it before exposing the film? Are you looking for halation as an effect? If you remove it right before development, you wouldn't need to dry the film.

I was wondering how much beer would have to be consumed to effectively influence development. And limited to IPA?
Imbibing too much beer will interfere with loading the film on the reels.

Speaking from experience?
Also dropping the reels and knocking the two sides out of parallel. <<hic>>

Drying will also be relative humidity dependent
FWIW, I mix 1 part isopropyl alcohol with 4 parts deionised water and whatever quantity of wetting agent needed, making a 20% IPA solution
If you have a 20% solution of IPA in deionised water there is absolutely no need to add a separate wetting agent as well, as the IPA performs that same task.
Damn, I'll run the drying test today
