Spray foam cans - what if improperly stored?

i just purchased a home and the previous owner left behind hundreds of spray foam cans still in the box. The only concern I have is that it was stored in the garage and have been frozen solid, likely many times over.

Has as anyone tried to use spray foam in cans after they have been frozen and then thawed? If yes, did you regret the result or notice any chemical breakdown of the intended purpose of the spray foam?

anything that you could recommend to test the foam to see if itís still usable or signs that it is not?

thank you in advance!

I think you are correct, having been frozen they likely will not be good. But, give one a try on some cardboard you can throw out later. Pick a warm day to test outside and be able to leave the results out there. My guess is, it will be obvious. Shake well.

I doubt there is anything water based in them, try one, bet they are still good.

Sell em on CL.

I agree, if water based - they're toast but if solvent based [and I assume they are] and the propellant is still good you should be able to use them.
