Solvent for epoxy adhesive

Hello Richard,

I too have used thin cyanoacrylate to repair ceramics in the past. Some are still in one piece, but others have failed, washing in hot water seems to destroy the bond overtime.

This is why I did a search for how the professional restorers do repairs to ceramics. They all recommend various two part epoxies for a permanent job, they mostly agree that cyano is more of a temporary repair. My experiences seems to confirm that.

Regards,

Andrew.

There are 'Dishwasher Safe' cyanoacrylate super glues available, see here, but there may be some limitations as to the materials being glued. The list of suitable substrates seem to be limited to glass, metal and ceramics which are all non porous which limits the exposure to moisture of the adhesive to the edge of the seam.

I often use cyanoacrylate acrylate (superglue) to stick discs and such to a flat-faced mandrel so they can be turned in a lathe. Heat is the best way of releasing the bond, and boiling in water works fairly well. The 'let-go' temperature varies considerably, I guess somewhere between 80° and 120°C. Some joints fail well below boiling point, others have to be boiled for several minutes, and a few stay solid despite protracted boiling and have to be released by gently warming with a blowlamp. I'm not sure why the release temperature ranges so widely, but suspect it's an age thing - old opened glue is inferior to newly opened glue.

Anyway, I think ordinary superglue isn't good for repairs that get hot. I suspect that repeated hot handwashing at 50°C would eventually break an 80°C repair and a dishwasher (90°C) would do it in short order. I doubt a 120°C repair would survive a large number of dishwasher cycles.

I don't repair china that might drop boiling water into my lap!

I use Devcon to bed rifle actions into the stock and naturally some excess squeezes out. I keep an eye on it and after about an hour it begins to firm-up. At this stage I remove the excess with a thin blade and wipe the remains off with an acetone dampened rag. As for cleaning my fingers I have found a squirt of hand sanitiser works well.

Most hand sanitisers are based on IPA, probably mixed with moisturiser

I just saw this post on Youtube, using hand sanitizer to remove epoxy. Have not tried it yet.
