Just figure I would post this up here for anyone else that might experience the issues...
I have several gallons of resin that have been sitting for about 2 months, as I took a break from the hobby... Somewhere along the line they got contaminated with moisture and it was like casting with expanding foam, an eruption of foaming resin right before it kicked...
Anyway there is hope...
After a little research, two DIY ways to fix it popped up, boil off the moisture on a hotplate... From what I understand as long as you hold the temp at about 250° F it won't hurt the resin but the water will boil off... Just cook until it stops boiling at that temp... Seemed messy and I don't have any 'disposable' cookware to do it with...
Second option vacuum boil the resin...
I went with option two and after 20 minutes of boiling under vacuum the resin is back to normal, just like brand new... As always expect 3-4x expansion of the liquid when under vacuum to be safe
I can't necessary say boil A or B as that varies by resin company, the side you want to boil is the size that doesn't form the yellow crustys around the lid, the yellow crustys is actually indication of that side having moister as well but it forms the crust and takes out the moisture on it's own... The "clear" side or the one that is generally pigmented is the one you want to boil in most cases...
Probably wouldn't hurt at all to boil both if you want...
Just wanted to post it up and maybe save someone else some money rather than tossing out the resin, just saved myself about $300...
