Does anyone know if you can apply Liberon finishing oil directly over Z-poxy and celluloid bindings?

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

Do a test on a piece of celluloid binding. You'll need to give it a few coats and wait a week or two for it to harden. I'm pretty sure it will take to it, after all it's just a modern Oil varnish with a whole ocean of solvents in it. It sticks to the metal can such that it no easy feat to scratch it off with a finger nail. Oil varnish drips that you get on glass vessels are also pretty hard to chip off once they are fully cured. Same when testing drying oils on a glass window, not easy to remove.

I have no experience with it but I don't think I would worry about adhesion as much as I would about a reaction of the celluloid to the oil. There is a possibility it could soften up the celluloid and if it does it will probably remain soft and or keep deteriorating over time.

I would take a piece of your celluloid binding and put it in a small jar and fill the jar with your finishing oil, let it set for a few weeks and see if it reacts.

Maybe someone else has had experience with it but that would be my main worry.

I have done truoil over zpoxy, didn't work so well. After a year or so the zpoxy got gummy where you hold the neck and slowly came out. Don't know a thing about liberon.

I have used Liberon on several instruments, but all on wood with no pore fill. For best results apply one coat per day and put a fan on it. You want each coat to dry and let all the VOC's clear out before applying another coat. I don't know if it will stick to Z-poxy or celluloid, but I would suggest roughing up the surface with 600 grit so the finish will have something to stick to. I'm interested to hear the results of your experiment and see some pics.
