How do you know when unibond is too old? If you test a sample piece and it holds well is good to go?

Ray,

The best way to tell when Unibond is too old is to examine its viscosity. The liquid resin will begin to thicken on itself. Fresh Unibond is about the consistency of maple syrup. It will become the consistency of refrigerated honey when it is too old. You don't have to worry about the shelf life of the catalyst, it does not go bad.

To extend the shelf life of your glue keep it in a cool place. The cooler the storage, the longer the shelf life. You can even keep Unibond refrigerated.

Sincerely.
Darryl Keil

Hi Darryl, do you know the approximate refrigerated shelf life for the Unibond resin?

My current batch (been refrigerated 16 months) seems OK since it's still quite a bit thinner than refrigerated honey, even while it's at about 38 degrees. My question is whether I bother to salvage the remainder after my upcoming veneer job, since the next veneer job after that is likely at least 6 months away.

The jug does take up a fair bit of refrigerator space, and if 2 years refrigerated is known to be at the limit, may as well just mix it all up for my upcoming veneer job to free up fridge space. Hate to waste it, but on the other had, letting it sit too long is the same as wasting it.

thanks

(PS your name came up as the one to ask, after asking the same question on Woodnet.)

The refrigerated shelf life can vary depending on a number of factors such a your refrigerators temperature, how long it was at our facility before you got it, what time of year it was and so on. Two years is a safe window in general.

If your next veneering job is six months away you should be fine. If it ends up being a lot longer than that then use it up.

Sincerely
Darryl Keil
