Anyone know from what sort of plastic Lisco & Regal, etc., film holders are made? I'm going to modify some and want to get the best adhesive match for the purpose.
Joe, I've just repaired some using Superglue, but a solvent type cement would be better. A few years ago I dissolved some 120 plastic spools in cellulose paint thinners and made a repair cement to fix some developing tanks, this worked extremely well, 25 years later the tanks are still robust.
I just tested Methylene Dichloride on a holder and would suggest that it is probably one of the best to use. It is the solvent cement used for acrylic. Try Home Despot or a sign shop might give you a bit. Just make sure you have a good fit between pieces.

It looks as if it might be the same product. I would google the chemical name so that you can be aware of the hazards involved in its use. Very unpleasant to get a trace in your mouth (BTDT) as it is about 200,000 times sweeter than sugar.
The easiest and most accurate way to apply it is with a hypodermic syringe. Plastic suppliers sell all glass ones and blunt needles. You can use disposables from the drug store but the rubber seal degrades rapidly. You can also get a one ounce bottle with a needle.
I've used gray PC-7 to repair a badly damaged 8x10 Lisco Royal. A little black paint and it looksed like new---and that was 5 years ago---that holder is still going strong btw.
