    Caulking for low temperature application

    What kind of caulk works best when applying at low or freezing temperatures? Such as for use in an active freezer?

    I don't know of any calk that will cure at or below freezing.

    I still use perma-gum for line and drain penetrations

    maybe some sort of two part stuff that cures with each other instead of the moisture in air?

    In our ice bins & ice-cream bin freezers we used Sikaflex in the manufacturing of these bins. There were at ambient for a few days though before commissioning.

    Cabinets was Permagum or ThumbGum & these were commissioned at the same time as application. After a few years the gum becomes brittle though , this was the only downfall.
    The primary function of the design engineer is to make things difficult for the fabricator and impossible for the serviceman.

    We use this stuff. Is not cheap and thicker than bear snot. Make sure you cut a decent size hole in the end of the tube. You can apply down to -70F in wet conditions.

    Sikaflex takes a long time to cure at normal temps. I'm not sure how it would cure in low temps. One thing about it is once it's cured, it's never coming off.
