Only a "portion" of it would have to be to put the name "Polyurethane" on the label. If you added some polyurethane resin to after shave you could then put on the after shave label "polyurethane".
Listen, I have read until I am blue in the face about POR and simplar products like ZeroRust. I have searched and searched to find all info I can. All I find is some mind blowing marketing, MIND BLOWING marketing. I recently tried to find a real test, head to head test on the web. One that put POR against etch primers, epoxy primers and other excepted forms of rust prevention. A test that would show POR against sandblasting and proper protection from industry standards like epoxy and a SS urethane. I found nothing. Now, if you search using "POR TEST RUST" or a number of other search words such as "salt spray POR objective". All I get is page after page, thousands of sites from POR distributors or POR themselves, or competitive products similar like Zero RUST. I want to see a REAL test, not one done by people with an agenda.
I must admit this site had some great info, that appears to be well documented.

I don't disagree that there are places for POR and the like. For instance, you have a floor that is pretty rusted with rust between layers of metal that would take major surgery to repair. If you don't have the time, money, skills, repro parts to invest in that particular car, use POR.
However, to use it, believing all the hype of the advertizing and some "testimonials" from guys who have put it on their trunk floor and the rust didn't reappear (notice I said "reappear" being it never really left so I can't say "come back")is not the way to go.
To use it on something like a frame that has been sandblasted where you could have used etch primer,epoxy and a SS urethane semigloss black paint (all with no sanding between by the way, wham bamn done in an afternoon)
(Joe, there is your answer) like every pro I have ever known would do, seems foolish.
I have said it over and over, go to any fleet of trucks, COKE,UPS, WALMART, they have MILLIONS upon MILLIONS of dollars invested. They have no products like POR on them. Go to a company who maintains equipment like blades and tracklayers, they don't use anything like POR on them (none that I have seen). Go to paint companies who have systems for these fleets, BILLIONS of dollars in paint sold every year with MULTI BILLIONS of dollars of warrantees backing the paint, no POR like products there.
PPG,DuPont, S-W could buy the POR company with what they spend on tissues in the executive rest room. If POR and the like were that great they would have been bought up long ago and copied or relabeled.
All the advertising of these products looks just like diet pill advertising. No proof, no REAL tests, just claims. They promise you results with no work, the American dream.
Go to any restoration shop, ask them if they use it. Go to any pro, any pro who does this stuff for a living and backs his work.
Like I said, there is a place for it. If you choose to use it for what ever reason, that's cool, you have the choice. I just like to point out to all who will listen what I know, so they will have some more info to make that choice.
