is there any thing that can be done withepoxy resin that is thick like crystalized honey

other than throw it out

what is the cause

tower ?

In most cases, epoxy has a small amount of solvent in it to create the desired viscosity. Over time, this can evaporate leaving very little 'solution' to the material. It is usually a highly unusual alcohol. Also, epoxy has a shelf life of usually one year or slightly longer. You would be better off catalyzing the product and disposing of it. You will likely find that the material will 'flash' very fast, get extremely hot (300F) and will not afford you the good wet film capabilities for application to the model. Hope this helps!

Dan,
Before you throw this away, try submerging the bottle in a pan of hot water. If this doesn't work, I've heard of people zapping epoxy in a microwave to heat it up and thin it out. I'd be very cautious with the time and power, making sure that the bottle is vented. I have not tried this micro wave procedure so I can not personally vouch for the results. I'm sure others can.

I've had the same thing happen as well. I use it until its's too thick to squeeze out, then pitch it. I started buying my epoxy in smaller quantities as a result, and buy from my LHS instead of mail order. That way I think it is "fresher". I suspect when mail order houses put the epoxy on sale, it's because it is getting old!

tried the microwave
20 seconds and a follow up 15
resin liquified
will mix some up tonite and let you know
Thanks
