First, a little background. It would be a mistake to call polyurethane glues “new.” Polyurethanes have been popular in Europe for decades and were first imported to the United States and Canada about six years ago by the Gorilla Group (which sells Gorilla Glue) and AmBel Corp.

So now we have six polyurethane adhesives to choose from — though glue-industry insiders suggest that the polyurethane market is crowded and that number might soon drop. But that’s another story. Here, in a nutshell, is what you need to know about polyurethane glue.
