URAC Shelf Life
« on: February 10, 2010, 04:00:13 pm »


I have had one pint of URAC 185 and the catalyst, opened, but in a refrigerator continuously, since one year ago this week. Is the product still OK? How can I tell the degradation?

I have used Urac similar to your with good results.
 The only way I know if it is bad if it doesn't set up.  ::)  Not much help for you there am I?

Well I may run a sample batch. There's enough there for several more projects. Thank-PD

Pete, most urac will be OK for at least a year. There will be an offensive odor to the resin when it goes bad.You'll know it. and don't worry if when you open the can that there are some brown streaks on top. Just stir them in.

 I've had some in my refrigerator over 5 years and it's still good.

Urac turns real dark when it goes bad, so I have been told. I have had it on my workbench for a year unrefrigerated and it was still fine. I think one could keep it refrigerated for years with no problem.
