After I read about it here, I bought a tube of 3M Fire Barrier
Sealant, but when I got home and read more I decided it wasn't what I
want.

I put it in the car to take it back and didn't think about
temperature. *It was there for 2 days, all of it 30 or below and last
night was 10F.

Am I obliged to keep the stuff and try to find a use for it?

The tube itself says to "store between 40 and 90F for maxmum shelf
life."

Whether you intended to or not, the caulk was likely compromised, and
it is a life safety item. *You know the store will assume you did the
right thing and didn't damage the caulk, they have no way of telling
what you did or didn't do, and they will put it back on the shelf.
Someone else will buy it. *The question is - would you want to be the
guy buying that compromised caulk? *Let that guide you.

I wholeheartedly agree with Rico's & Red Green's comments.......
returning potentially compromised material (especially something like
a fire protection product) is unethical.

But here the are the "Storage Conditions" from the 3M product
information

5. Packaging, Storage, Shelf Life

Packaging Product packaged in cartridge or pail is enclosed in HDPE
plastic containers, sausage is packaged in aluminum foil wrap
Storage 3M™Fire Barrier Sealant CP 25WB+ should be stored indoors
in dry conditions between 40°F and 90°F (4°C and
32°C) in the original unopened package. Avoid repeated
freeze / thaw exposures of the 3M™ Fire Barrier Sealant
CP 25WB+ prior to installation.

Shelf Life 3M Fire Barrier Sealant CP 25WB+ shelf life is 12
months in original unopened containers from date of packaging
when stored above 68°F (2°C).



the operative phrase is " Avoid repeated freeze / thaw exposures of
the 3M™ Fire Barrier Sealant CP 25WB+ prior to installation."

Looks like you're home free with only a single freeze thaw cycle.
What's expiration date or date of mfg?
