Hi all i noticed my 5 and 15 minute epoxy resin has start to crystalize i heard some one mention you can heat it up with a heat gun or put the resin bottle in hot water to thin it out. My ? here is by doing that with if affect the epoxy's bonding ability and long term strength ? Regards Andris Golts ?

I tried some 10 year old 30 minute epoxy the other day and it worked fine.

normally the Hardener crystalizes i have noticed with old z-poxy resins.

De-crystalize it with heat. ie... hot water, microwave, hairdryer

Then mix up a test batch and make sure it cures. If it's stored properly and it still cures in the correct time; I wouldn't worry too much about dates.

Later
