    New question here. Will Stan's freeze?

    Anyone with stans sealant in their tires should be asking this questions.

    Did I hit a big taboo or what?

    No one will answer this qustions, that makes me worried about tire sealant.

    Everything Freezes at some point. I left a bottle of Stans in my garage this winter and it was rubbery hard and squeeable, but not liquid anymore. It worked fine in the spring after the thaw.

    Did you actually attempt to shake up and try to pour some out? Perhaps it only thickened.

    I believe that Stan's sealant is combination of latex and acetone or something similar to acetone. I think this because I was cleaning my Stan's 2oz bottle attempting to use alcohol and it hardened the latex instantly. I poured in paint thinner and it broke it back down.

    Anyway the freezing point of acetone is around -140F. If Stan's sealant is indeed acetone based (or a solvent with a similar freezing point), then you'd probably die from frost bite before your tires would have a problem. Scientists use acetone or other similar products to mix with dry ice to make a very cold slurry because even dry ice doesn't freeze acetone.

    I rode in sub 32 deg conditions last winter with Stans and had no problems. Temps probably in the high 20s, so it might not be the best indication, but I wouldn't worry too much about it.

    The real test is just to pour some in a container and set it outside in cold temps. Should answer any questions.

    I did not try to pour any out. It was around 10 F in my garage and I picked up the bottle wondering about it's status and it felt like solid rubber. Maybe the solution was old or it had separated by sitting in the cold as the solution is a mixture more than a percipitant compund as it needs to be shaken before use as the latex sits on the bottom.

    Its a valid question, and I dont think that you hit a big taboo, so much as I'm not sure that too many people know for sure how the solution will react under freezing temps, and whether or not its OK after it thaws.

    Regarding your concern, one possibility is add a few drops of automotive anti-freeze to the solution. I know that some people do this with homemade tubeless solution. It may work with Stan's, but I've never tried it. I'm not sure just how cold it gets where you live, or when its cold enough to call off a ride. It never gets that cold where I live, so I've never really thought about it.

    Yes, Stan's sealant can freeze but it will be WELL below zero degrees F when it does.

    We do a lot of snow rides in NY on packed snowmobile trails and the sealant works just fine.
    Please do not use the forum PM or e-mail function for business related questions. I can be contacted through our website. Thanks!

    Test it yourself! One the the easiest things you can do.

    Pour a couple of oz. in a yogurt cup and stick it in the freezer. Wait a day. See if it froze!

    The trouble with common sense is it is no longer common

    Good sugestion although I do not have any Stans.

    I was mainly asking for the purpose of what it does in the tire when the temps get below freezing.
    Will it make noises and make the ride roughier?

    Just curious
