RE: Re: Non-Volatile Urethane Thinner?

Gorilla Glue would be an example of a urethane glue.

I have not heard of (poly)urethane being used as a glue, but the stuff is used extensively for clear varnishes, and when pigmented, for hard-wearing floor paints. When used as a varnish or paint, it is thinned and cleaned off brushes with mineral turpentine, which does not dissolve polystyrene foam insulation..

For woodworking, I usually use polyvinyl alcohol glue, which can be washed off with water; or for exterior use or for greater structural strength, epoxy glue. For small
repairs where rapid setting is required and no gap-filling capability is needed, "super glue", which is cyanoacrylate, can be used.

Subject: [The Chemistry Cluster] Non-Volatile Urethane Thinner?

What kind of liquid should be used to thin Urethane woodworking glues that
is not corrosive to foam insulation? I need to re-laminate some FRP
sheet with its foam backing using capillary action and roller pressure to
distribute the glue (so it needs to be thin), but in the realms of
woodworking the only suggested thinner is laquer thinner which I fear will
eat the foam. Someone here should know of an answer to this,
surely?

Thanks,
