Storing Sealants like 5200

I called GE to complain because some silicone before the expiration time did not cure, and I got free coupons.

I wonder if they will continue to be as accommodating, having been just kicked out of the Dow.

Saving sealants

I store all sealants and caulks in a container which I vacuum pack. They stay fresh indefinitely. I also store all spare parts in bags which I vacuum seal.

Seems like a lot of folks vacuum pack their things.... Can you educate us on what vacuum equipment you use... options and bags needed?

Thx

I use an old Foodsaver. Similar to this. https://amzn.to/2yvVWSv

Here is another popular (and inexpensive) vacuum sealer on Amazon. https://amzn.to/2ys91fI

We bought a small one that is low on extra features, but easy to store.

It’s good to vacuum bag your flares as well. The retail packaging isn’t very water resistant.

I noticed that 3m 5200 comes in 1oz, 3oz, 10oz or 5 gal pail.

At the marine electronics place I worked , we got a lot of tubes that only after a half season or so of storage, the whole tube had hardened.

Now that was a few years ago, maybe things are better, and freezing certainly may help but I would still be leary of storage time.

Most things that self harden....usually do.....

It is a Food Saver, GameSaver Big Game model. It operates on both 120 volt A/C electric as well as 12 volt D/C current. In addition to Food Saver bags we have Ball Dome canning jar accessory and Food Saver cannisters of varying volumes. We use one canisters for all sealants and caulks.

We lightly spray spare machinery, such as a starter, alternator, water pump, etc., with Patron Plus spray lubricant prior to sealing them for storage.

As an aside, I use Patron Plus lubricants in or on ALL mechanical equipment and fuels, and Royal Purple oil in ALL engines.
