UV Adhesive remover


Recommended Posts

At my last job when we glued crystals into cases we used UV glue and cleaned it up with "Trichlor". The stuff worked GREAT It only removed the glue on the surface and I could get a very very clean seam. BUT I can't seem to find any place that sells it. So I was wondering what all of you use to clean up hardened UV glue. 

 

Thanks for your time.

not surprised you can't get it any more. I assume that it is trichloroethylene which is now banned almost everywhere due to its carcenogenic properties.

Does acetone not work at all? Failing that is it not possible to clean up any excess glue with IPA before curing it under the light?

Since you are in the US, you can get it, search ebay for  trichloroethylene.  It's gotten expensive, though, 500ml for about 50$ US. Nasty stuff, too. Be very very careful when using it. I use it as "One-Dip" for hairsprings and jewels, and try really hard not to inhale any fumes or get any on my skin.

A solvent often used as a substitute that is not quite as dangerous is Tetrachloroethylene, otherwise known as "perc" or dry cleaning fluid. I've found it sold in auto parts stores as brake cleaning fluid. I don't know if it will work as well in your application, as I don't use UV glue.

We had something in Sweden called bräkleen from CRC . But don't now if that has tri any more? Tri is not very good for the environment.

I remember once using 'triche' in my teens (many years ago!!) to clean some cycle parts in my dads shed.  My dad had a big bottle of it.  I can remember my head starting to spin (not literally!!) after only a few seconds.  I got out quick to recover.  Chucked the stuff and closed the bottle very tight!!  Never used it ever again !!!!

To think that it was widely used in the engineering industries as a degreaser/cleaner is frightening.  No wonder it is banned in the UK, although I think it can still be used under license with very strict rules and requiring very sophisticated and no doubt expensive ventilation/extraction/solvent recovery plant. Most of industry moved to other products as a result.

I believe it was originally developed as an anesthetic.

My other secret vice, other than watch tinkering, is reviving dead iPhones. I use UV glue on the screens and that cures to a rubbery texture. This peels off with a bit of rubbing and I would have thought a piece of peg wood would do the trick here.

I agree with the often repeated idea that glue goes with watches like sardines go with custard but why use a UV glue to further complicate matters?

Using a solvent on glue just turns it into thin glue.

Just done a straw poll in the phone community. Fluids used to remove the glue range from engine oil to electrical contact cleaner via WD 40 and olive oil. Plus mechanical removal by rubbing, scraping etc.
An almost 100% vote for IPA for final clean up.

    • Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!
    • Happy to have helped, great way to start the day with a win! 🥳
    • Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor. 
    • I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂
    • Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
