Hello:

Seem to be seeing more and more ads these days for "Polyurethane Glues."

They claim that they are as strong as epoxies, but with the big advantage of
being only a single component.

a. Are they truely as strong as the typical two part epoxies like the
Devcon products in the double-syringe
packaging you see in all the hardwarfe stores ?

b. Pros and cons of polyurethane adhesives ?

c. BTW: Is this what that Gorilla brand of glue is ?

Thanks,
Bob
