Important to store in a dark, dry place. Polymerization is initiated by
moisture in the air and can be accelerated by light.

Interesting observation. I do keep all my glues in a garage drawer.

Similar for Gorilla polyurethane glue which I find worse as it is
packaged in a polyethylene bottle and not moisture impermeable.

There are so many gorilla glues I can't keep track which one you're talking
about. Are you speaking about the honey-colored gorilla glue that foams
when you use it?

It's "polyurethane"?

Is there a similar "polyurethane" glue I can compare it with?

I prefer 2 part epoxies that can remain stable for decades.

I buy the epoxy tubes of liquid and the epoxy tubes of putty.
The putty dries out over time.
