Question for chemists and box builders alike

[PV Audio 5,000+ posts]

Okay, tonight when I was doing one of this week's builds, I noticed something interesting. Two weeks ago was the last time I had built an enclosure, and I finished another on sunday. But tonight, I used an older bottle of titebond 2, and when it dried it was literally white as baby powder. Quite powdery to the touch as well. The joints dried yellow as usual, but the excess (after wiping, not the beads) dried bright white. Why is this? It has been extremely cold, but I dunno if that's it. I'm just wondering because I don't want to be selling shoddy enclosures just because mah glue's gone bad //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Input? Thanks. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I've seen what you are talking about.

Don't think it hurts integrity.

I'm just hoping it doesn't, because the joints were yellow, but the excess turned white. Literally like baby powder white. Weird as hell. I'm thinking that it has to be the cold because I bought it only a few months ago and used it two weeks back when it was mid 40s with no problems, and I've had the same jug of T1 for 8 months and it still works fine (used about 3 weeks back). This is the newest bottle I have, and even when I tried using the T2 from my smaller bottle, the same thing happened.

And BTW it's between 0 and -1 here right now, depending on the station.

TBII did that with my last enclosure as well, and it was piss cold, colder than I've built in before.

Didn't seem to mess with the strength of the bond, but it DID take more than twice as long to cure....

LOL you get hit by that snowstorm earlier this week? Indy got the shit beat outta it. Two snowdays in a row....and we've never had a snowday before.

We only got like 3", but I'm out in BFE surrounded by corn fields, so it was equilavent to 12" lol

All my excess glue turned white, i kinda wondered the same thing myself. Kinda odd, but i didn't think anything of it. Probably the cold. It's like 2 degrees here now with like 7 inches of snow on the ground.

Its because of the cold weather //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

If you read the bottle...says something like don't use under a certain temp.

Yeah, 40 degrees IIRC.

Yeah, happens when it's cold. Usually if any extra glue falls on wood, you can use a damp cloth to wipe it completely clean off. When it's cold, it leaves a nasty looking white patch.

LOL under 40 and I'm using it under 4. BRILLIANT!

And yeah Pat, that basically describes the situation.

Under 4 degrees? You must be a diehard sub box builder. hell i thought i was bad. my dad parks his truck in a big 80 x 40 foot shop and it stays around 40 degrees in there, just to keep shit from freezing. and i cant stand it.

if it was because of the cold, the joints and the excess would be the same color....since they are the same temp. i think it is because of it's thickness in the joints...the thicker the more yellow it will appear.

yeah, my a$$ is tired of shoveling here too....dam snow blower is in the shop.
