Has anyone tried that UV cure glue?

What's it like, any good?..

It's not "glue" as such it's a liquid plastic resin that sets under UV
light..

I have used it to reattach the lens caps on the LED backlight on a TV
and to fix a broken nose piece on a pair of magnifieying glasses.
Excellent for both of those uses, but how good it is for more mundane
uses? I haven't tried

Isn't that what dentists use for setting fillings and attaching crowns
to teeth?

Yes, and re-attaching rear view mirrors to windscreens. Though whether
all these types of UV cured glue are the same, I don't know.

And, many years ago, re-attaching the catches to quarterlights.

Dentists, according to my dentist, now uses a blue light cure - not UV.

I think the UV ones have been phased out, largely due to the impact of UV on the dental staff.

They were using blue light 30 years ago. In those days it was
produced by filtering the light from a quartz halogen projector
lamp before sending it down an optical fibre light pipe.

Nowadays I imagine blue LEDs would be the preferred light source.

Yes it has also been used successfully in space, outside apparently, so
maybe it does not require air either.

LEDs are, most certainly, the choice. Gets the exact wavelength required and can easily be run from a battery.
