Is polyurethane glue new?
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. (which sells Excel). Pretty soon the big glue manufacturers took notice and introduced their own lines of polyurethane glue. 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.
