UHU, der Alleskleber

[darkoshi]

It seems that UHU liquid glue, the kind that comes in a metal tube, stops working after about 10 to 13 years. It has become very liquid, and no longer has enough adhesiveness to even glue two pieces of paper together. Its cardboard box says "Produkt des Jahres 2004", so that gives me a rough idea of its age.

I hardly ever need paper glue, which is why it was so old.

It may self-polymerize, rather than waiting to be stuck to something. That's a failing of a lot of modern chemical adhesives.

I'm used to glues drying out rather than liquifying. I think this was the first time that happened to me.

Now that you mention it, I wonder if the glue is hygroscopic and has slowly absorbed atmospheric water over time. I've never seen a glue fail that way either. (But, here, that would be unexpected.)
