3M 5200 April 18, 2021, 10:05:08 am Anyone know what the shelf life is after opening the small tube?The bigger gun tube needs to be used fairly soon in my experience. Great stuff.
Re: 3M 5200 Reply #1 – April 18, 2021, 12:12:32 pm I used some, then put it away, probably for several months. When I next took it out, it was solid from the cap down about an inch. An old drill bit got me some more. I then stored it again. Next time I took it out, it was hard too far for the drill bit to clear. I put a small cut in the side near the bottom, used some, and sealed the cut with tape. Next time, that side was hard, but a cut on the other side, getting the final use out of the tube. I don't think there is a shelf life, per se, but with brief contact with air, a considerable portion will harden.Ken F in NM 4 Likes
Re: 3M 5200 Reply #2 – April 18, 2021, 01:19:50 pm As long as the 5200 is a still liquid, it should be usable.3M’s 5200 is cured by absorbing moisture from the air. Once the tube is opened, even with the cap reinstalled, air leaks into the tube. Sealing the caps with a couple tight wraps of electrical tape will help prolong its sheft life, once opened, by reducing the inflow of air.Larry 2 Likes
Re: 3M 5200 Reply #3 – April 18, 2021, 01:41:17 pm "Sealing the caps with a couple tight wraps of electrical tape..."My preferred choice is to plug the nozzle with an appropriate sized nail. It closes off air entry and keeps the channel free from being clogged! Then, when needed again just pull the nail free and go back to work. 5 Likes
Re: 3M 5200 Reply #4 – April 18, 2021, 01:54:06 pm I’ve been able to get a longer life from it by squeezing out a small ball of the adhesive on top of the tip, leaving that to dry and pulling it off when using it again. Also, I’ve just replaced the tips. But I’ve not stored this for more than a month at a time. 1 Likes
