I have stored mixed 2 part epoxy paint in the freezer for several months and then used it with no problems. Has anyone tried this with epoxy resin. Seens to me that resin mixed with slow or medium hardner could be stored this way for short periods of time, a day or two.

Re: Storing mixed epoxy resin

Never thought of that, though I have had problems when using epoxy resin when the temperature dropped more than I thought it would. Everything stayed tacky so I had to add more drops of hardener.<br /><br />My question is - how did the ice-cream taste after this? :)

When spraying resin,some times you can put the pot in a ice chest to slow it down.It works some what,but it is not good to do,breaks down the chemical reaction.

Re: Storing mixed epoxy resin

My experience is that it stops the chemical reaction. We have put 2 paint guns with mixed paint in the freezer. And finishing resin in the freezer, I have not tried it with epoxy, but don't see why it wouldn't work.<br />The container should be tightly sealed or like Bayman said, your ice cream might not taste to good. :)

I’m not sure I would be putting anything with toxic fumes into the freezer with food. The freezer’s plastic liner will absorb some of the chemistry. On the other hand, ‘woman’ is forever getting on my case for the stuff I put in the dishwasher; one of the finest automatic washing systems for mechanical parts invented by man.

18rabbit<br />Thanks for the idea but I think I would be dead meat if I tried the dishwasher trick. I don't put it in the freezer in open containers I use a mason's jar

Re: Storing mixed epoxy resin

The high tech boat building guys used (in the 70s)to have a process called PrePreg. It was mixed resin kept in the refridge until used when vacuum bagging hulls and decks. Don't know if they still do it.

Yes Bondo I am the one and only.<br /><br />After that jerk launched his verbal assault on you, I decided I did not want any part of that crowd. You were right...his "holy book" was wrong.<br />Nicer people over here. :) <br /><br /> I bought a truck load of parts and other stuff when my cousin retired. I now have 5 outboards, and I am an inboard man. I will need some help. :)

Re: Storing mixed epoxy resin

It must be in an air tight container like Buttanic said. The paint will start to gel after 4 days at 22 degrees. And it smells!!<br /><br />I have kept resin for up to a week with no problem, and it worked fine.<br />Paint or resin must come up to room temp. or outside temp, before using.<br />With resins...use a paint stirrer on a electric drill, we spin it for 1 minute, and never have any problems, I don't think you can get it mixed that good with a stick. :) <br />Another resin trick, after it is mixed, put it in a aluminum foil baking tray, to spread it out. The more concentrated the resin, the quicker it will kick off, I can get more than 15 more minuted of open time, by spreading it out in a tray.

Re: Storing mixed epoxy resin

Are you guys bringing that back to near room temp,<br />Or brushing it on, right out of the freezer ?????<br /><br />I've never tried that trick before.... Have used the spread it out method though.......

Hey thanks, It would be a little slow setting up right out of the freezer. :)

Re: Storing mixed epoxy resin

I am sorry but are you storing Poyester or 2 part epoxy? And for gods sake why? I see no point unless you don't have a clue as to how much you will need.

Polyster<br /><br />And for gods sake why?<br /><br />Telephone rings.<br />Customer comes by.<br />Starts to rain.<br />May need some for another job tomorrow.<br />Hey, boss man we need you over here.<br /><br /> I see no point unless you don't have a clue as to how much you will need.<br />--------------------------------------------------<br /><br />Even though I buy in bulk, remanufacturing a boat is a labor intensive job and employees cost money, and I don't waste product, be it paint or resin. Why would I throw away $35.00 worth of paint, that I will may use in a day or so. :)

Re: Storing mixed epoxy resin

I haven't checked lately but poly resin mfgs I dealt with used to spec that poly resin had to cure within a certain window of time after adding catalyst or the resin wouldn't reach it's max Barcol hardness. The resin hardens and feels ok but it doesn't get as hard if it misses the "window". The resins I used had to kick within a few hours of adding catalyst or they didn't cure at their max hardness. Poly continues to cure after it is tack free...similar to concrete but a much shorter period. It seems to me keeping catalyzed resin in the fridge would make this an issue worth looking in to.
