Reviving Old Epoxy

Post by johnnemo » Sat Apr 21, 2012 10:30 am

I have some epoxy that I bought just over a year ago. It has been stored in a somewhat climate controlled area (garage). I pulled it out this morning and noticed that the Part A (epoxy) has a white sediment in the bottom of the bottle. This is System Three standard epoxy.

Is there a way to "bring it back to life"?

Is it a bad idea to try to use it?

I seem to remember someone having a similar problem on the forum and a solution that involved heat.

Warm it up till the crystals disappear. Do a test strip to see if it's ok.

Hot/warm water bath will bring the crystals back into liquid. Just put the water in a pail/bucket and drop in the jug(s) of epoxy and let them sit a while.

As others have said gently warm it up in warm water bath. Stove and a big pot works well. You don't need the water to boil.

There should be no problem using the epoxy. It's a known issue with older epoxy but it doesn't affect it's strength at all.

I can confirm that it will just as good as "fresh" epoxy.
Here in Florida, when that happens (very rare) we put the jug in a black plastic bag in the sun and that's warm enough to get rid of the crystallization.
