In the refrigerator. It will last almost two years.

I forgot some catalyzed VE and some Microlite in the freezer and found it about a week later. After about 10 min. at room temp. both were workable. I just tried it on some test pieces to see what would happen and it seemed to set up properly so I would expect that if you keep the resin cool it should last a long time.(if you are going to store the catalyzed stuff in the freezer keep it in a covered container, it stinks up the place) TT

I got a gallon of vinyl ester resin from spruce 2 weeks ago....opened it up and it has congealed. Not all but very "clumpy".

I wont use it...I promise......
I just got off the phone with spruce. They changed again. The new stuff has a shelf life of 60-90 days from the time it is manf....What a Joke..!! So by the time spruce gets it it is 2 weeks old, I get it 60 days later. The factory rep also said it was no good. So spruce is sending another. What happened to the old stuff...It worked fine...

Mike, I bought a gal from Spruce about 8 mos ago. I still use it and it's still good. I keep it in the frig when I'm not using it and it seems to last a long time. Ed Lynch mixes it with MKRP and puts it in the freezer and can still use it the next day. Try it it works. Tom Saccio

Aircraft Spruce has gone through a couple of itterations with regard to the VE they supply. It was traditionally greenish and clear and then several years ago they started shipping the "tannish" kind of cloudy stuff.They switched back to the green stuff some time ago. I bought some 3 weeks ago and it was still green. When the tan stuff started appearing I checked with Ashland and they said it was good but some promoter or something had changed the appearance but it still performed exactly the same. TT

Hi Tom, I talked to ashland as well as spruce few days ago. I have the tan stuff from spruce. The tech at ashland said the resin was bad and not to use it. She also said the resin was good for 60-90 days from date of manf. The person at spruce said they changed a few months ago to the tan stuff. I have ordered resin from spruce over the past year....clear, green, tan. The green was out in the heat/cold/humidity until 2 weeks ago and was still good over many months, untill I used it all. This tan stuff is crap!!

I'm pretty much through with anything but small attachments. My current can of resin was getting a bit thick. I got a small can of styrene from the local Tap Plastics store and thin with it a maximum of 10%. It goes from clear to greenish as usual, but goes off @ 1% mekp about the same as it used to @ 2%. Tap says this is to be expected. Interesting. I would never buy vinylester from Tap though. Talk about questionable shelf time!

I purchase ester resin from spruce. Put it in the refrig and it lasts for years.
