Tommie clearly said "Probond Polyurethane Glue " in his post so he's not guilty, but a lot of other people do use the name "Probond" loosely when they really mean only the polyurethane. The "Probond" name actually is used for a whole line of adhesives Borden (Elmer's) makes, including polyurethane, aliphatic resin, and others. But this is not so clear when all you see on a shelf is one of the products. The company could do more to make this point clear to its customers.

30 or so years ago modelers started to use other adhesives besides Ambroid, and one of the first was Titebond aliphatic resin. I never liked the way it behaved but eventually found Wilhold aliphatic and it was great. Wilhold has gotten hard to find (at least around here where I live) for some years now, but I have been very happy with Probond aliphatic for wood joints.
