Gorilla glue is a polyurethane...
Somewhat surprisingly, in the glue test FWW did a couple of months ago,
the polyurethane came in at an average strength of 58% of that of the
Type I pva which was the strongest. That said, most of the joint
failures tested with all glues were either wood or wood/glue combined
failures with only a small fraction of the loose-fitting joints being
100% glue failure. But, of those which were, the polyurethane was the
largest number.
Cleanup of the water soluble glues is much simpler than the
polyurethanes which need acetone or another solvent and the foaming
characteristic is a major detriment to their use in my book for anything
not absolutely requiring the waterproof (as opposed to water resistant)
characteristic.
