I have ordered a large bottle of acraglass and
expect it to last me for some time.
I noticed one review, stated his had set up
when he hadn't used it for some time.
Is there anything you can think of that might
assure long term storage and use. Thanks for the tips. Kenny

I order the large bottles also and they last me a couple years usually. Keep them out of direct sunlight, don't let them freeze (or even close to that) or they will slowly crystallize. Write down the date you received them on the bottle by the batch # so you will know how long you've had them in case they do go bad. I try not order my supply during winter if I don't have to, shippers will not try to keep them from freezing.

I just keep in my shop; if/when, after literally years, it starts to crystalize, put into the microwavce for a few seconds; it will turn smooth again. A lot of good epoxy has been thrown away; some by me.

Bingo! This has worked like a charm for me for years. Like dpcd said, only a few seconds at a time and only "nuke" the amount you'll be using at that time too.

I nuke the whole jar and that will rejuvenate it for another few years.

Considering the microwave to be too high tech, I've always just immersed crystalized glas in hot water. Regards, Bill

Thanks fellows your information may save me a bit of pain. Kenny

The general rule for long term storage of catalyzed adhesives (epoxy) is to refrigerate them until you intend to use them.

For anaerobic curing agents (IF "Loctite", Cyanoacrylate(super glue)leaving nthe bottles on their sides to maximize air contact is adviseable.

i have since changed to marine tex gray for bedding big bores...

i just keep it in my AC part of the shop, lasts for years

Funny....

I use slow cure JB Weld and just buy fresh as I need it

I have a couple of old "Acru-Glas" kits . . . As in really old (90s).

Will it perform correctly as long as resin and hardener still seem to be normal and react?

I use Marine Tex on some jobs..It lasts a long time but will get hard in a year or two..On some jobs I may use Brownells liquid thinned to waterproof inletting..Sometimes its just better to buy small containers and if it goes bad just toss it and get new can or bottle.

TClouis, just toss it and get a new kit..

I never throw away acraglas. Made in the 90s; thats new to me. When/if it turns to sugar, I nuke in the microwave, as indicated above. Never had a problem.

I use Marine Tex exclusively for bedding now. I buy it in the quart sizes and I have never had it go bad yet. Mind you, I am forever running out of it too so maybe I'm not letting it age properly. lol

What I do want to know ! ! ! Am I the only guy on the planet that uses the thin, generic Krazy glue, like the Satellite City cyanoacrylate glue for sealing wood inletting? Or are you the only guys that don't use it?

No but I am going to start because if you are using it, it has to work.

I triple up a 30 caliber cleaning patch and hold it in a hemostat and dip it in the evil crap and paint it on until the patch goes hard as a rock. (about 30 seconds) Then I pry the patch out with pliers, put in a new patch and continue. I usually put on 2 coats. Less than ten minutes from start to seal, to rock hard and ready to put together. It looks good too. I use the crap to fix small scratches too. You can buy the spray accelerator too but you have to be damned careful with it and spray lightly at about 12 inches or the glue will boil and turn white. You have to play with the accelerator a lot before you use it for real to get the hang of it. Most times I don't use the accelerator. I have been using the Krazy glues for this application for 15 years now.

Just about any liquid can be made to last much longer if you'll store it upside down so the air is trapped in the bottom of the bottle. Same goes with paints, this way the gases in the stuff can't escape and dry it out.
