Title: UV-cured cyanoacrylate glues?
Post by: klugesmith on November 09, 2019, 06:38:53 PM
I want to bond some clear Mylar film to itself, and UV-cured glue seems like a thing to try.
The ideal material would have low viscosity, and not cure too fast from pressure or exposure to air.

The closest thing available at hardware store is "ZAPIT" from Superglue company.

Comes with a curing light in the form of a little key-chain illuminator, with 1 LED and room for 1 coin-shaped battery.  At first glance that's laughably small and low in radiant power.  At the opposite extreme are UV radiators for curing ink in continuous printing presses, that roll at many meters per second.

Package says the user is in control. :-)  If you skip the UV light, the glue cures anyway within 1 or 2 minutes. Sounds like a bug, not a feature.
Anybody here have a better suggestion?

I know that we (at least used to) use Loctite 4305 at work. This is UV cured cyanoacrylate but also cures with moisture or just with age in the bottle, so may be along the lines of the one you've already found.
