a list of the fastest-curing types of adhesives
less than a minute
These types of adhesives are strongly preferred for manufacturing lines, because there's a pressing demand for super-short cycle times, and having an adhesive that cures in 90 minutes is a severe limitation to that.
dual-curing adhesives can partially cure in seconds — the portion of the joint that's exposed via optically clear material cures in seconds, with this portion serving as a kind of "clamp" that helps the portion of the joint that's in a shadow to cure over a longer period of time
Preactivated light-curing adhesives can cure in ~20 seconds. "Preactivation" is similar to "activation on the flow". (TODO — what is this black magic called "preactivation"? I'm still trying to understand this bit.)
On manufacturing lines, various adjustments will be used to minimize curing time, such as curing inside an oven.
