Hey all,
Is anyone out there familiar enough with this stuff to have a good feel for what its setup time is?
Thanks in advance.

it's been a while, but my fuzzy memory says you have pretty good open time, something like 15 minutes, then leave it in the clamps overnight.

Wonder if we're both thinking of the resorcinol version, which was my dad's favorite precisely because of the long open time.

Is that the brown powerder glue that you mix with water? If so, you'll get 15 to 20 minutes of open time.

I *think* resorcinol is the waterproof version of Weldwood, both being urea formaldehyde...

Doesn't look like it. Formaldehyde common, other different.

Not quite. "Resorcinol" glue is either resorcinol-formaldehyde or phenol-resorcinol-formaldehyde and is rated by the Forest Products Laboratories (major research institution) to be "structural fully exterior", while they rate urea-formaldehyde as "structural interior". I don't recall which formulation Weldwood uses in their "resorcinol" glue--been a long time but I seem to recall phenol listed on the label, in any case it's a quite different product from their "plastic resin" glue.
Note that "Weldwood" is a DAP brand name that covers at least as broad a range of adhesives as "Loctite".

The responses you're getting saying 15-20min seems odd. DJM is fond of using "plastic resin glue" when he needs very long open times.
Gives the impression it would be "hours".

gives the "hours" impression (albeit at cooler temps) too.

Pot life, according to the manufacturer, ranges from 30 minutes to 4 hours depending on temperature, and they say it should not be used below 70F.

Actually 20 minutes sounds about right. I just wanted to confirm. It's probably more like 20-30, though. I think you're confused about the difference between open time and pot time.

could well be. it's been at least 10 years since I've used the stuff, and we all know what them rolling decades does to the memory....
plus, where I live, hot is more likely than cooler temps.

Heh. Hopefully you didn't take that the wrong way.
