Refrigerated old DuraCoat any good?

[VaniB]

My NOT so usual instance is that I keep batteries, cements, and paints refrigerated for years in a fridge draw. The 3 different refrigerated DuraCoat 4 ounce bottles of paint I have all showed paint pigment that was separated & had settled to the bottom of the bottle. When I shook them, the factory mixing ball inside the plastic bottles got loose and soon rattled. After the factory advised 3 minutes of vigorous mixing, the paint looked mixed, uniform, and usable again. THIS STUFF IS 7 YEARS OLD! I'd really prefer not to go through the trouble of making a mess and shooting it out of my gun just to test it. Does anybody know?

I suppose I can always call DuraCoat paints to ask them about the longevity. But perhaps they have never tried refrigerating their own paints for 7 years to know for sure. lol

Give it a try , only way to know.

Please let us know how it works. I have some in my fridge that’s going on 3 years old.

Don't wait up on me for the results guys. I don't have any projects planned for the near time future. The only reason I'm asking is because the wife and I are having a new refrigerator delivered today and the wife is raising hell about me storing my hobby supplies in the new fridge. lol Either I buy a new mini fridge for about $300, or toss everything. But I need cold storage for batteries anyway.

Buy the mini fridge and put it in the shop/reloading room. Good for beverages while "working". Flat screen, recliner in same room would be a plus.

Don't know how well it'll work with those small bottles but;

We do "right much" paint work here and it's a rarity I don't purge a can before it goes back into storage...... Argon,being heavier than air is used. Just go over to the welding station and,getcha some. Works for purging scopes too. Larger molecules than nitrogen so lasts a bit longer(purge/reassemble scopes inside clear plastic bags).

I'd definitely be running a test panel before shooting questionable paint on anything worth a darn.

Great plan : )

The duracoat doesn't go bad but the hardener does.

Batteries of most any type do best at 77 degrees F.

If you slow down the molecular activity of chemicals and compounds including that of batteries, glues, and paints via a fridge temp of 37° it greatly prolongs the life. Batteries, paints and already opened CA bottles I had stored in the lower crisper draw for many years are still good. I have yet to ever discover a single battery cell that corroded and leaked in the fridge, but often find corrosion with batteries that were simply sitting inside of the electronic device at room temperature. Every battery I have ever taken out of that fridge still works well and takes a charge. My DurapCoat paints and hardeners are labeled 2013 and are still fluid, and many of my batteries were stored away earlier then that. I've read it's possible for condensation to enter a battery and ruin it in the fridge, but I have never experienced that.
