There are uv cured adhesives as well.
Set within a second of exposure.

Very handy if you are trying to glue a horse or something else that's trying to move around!

Also the glue used to fix rear view mirrors to your windscreen back in the 80's - hold for 15 mins.
Best done in the summer because winter UV is poor and don't forget to tell the mirror not to fall off in December.

Was speaking to my dentist...they use a UV cure adhesive to hold dental stuff in place while the slower cure stuff sets.

I get the Uv cure resin from Austria, then add pigment to get the colour I need. These are parts of an igniter for a Hetzer tank I am reproducing. It’s printed submerged in resin and the various leds only cure specific areas to build up the layers

Been using those for a while, extensively used in dentistry as noted by @Pigeon_Droppings2.

UV curing laquers have been around for donkeys years for industrial use. I built one in the early '90s out of a old machine for a timber moulding. manufacturer I worked for. Timber in one end wet, stacked other end on top each other.
