Thread: PUP (polyurethane polymer paint)

Blknight is the expert on this. The main dangers are sanding it etc. The Army use it on all of the Aircraft, cars and trailers. not sure about the ir suppression but I have yet to see anything rust with it.

Do all PUP's have IRR qualities?
Why do my Perentie's have PUP warning stickers all over them?
What's the hazards in sanding PUP?
I've been on the protec website and chemalert and can't find a MSD. The only thing that mentions polyurethane is Dulux house paint.

So, can anyone tell me about PUP, IRR, why the ADF use it, what's the hazards in using it and should i re-paint with PUP or use an enamel or 2-pac ???

Thanks in advance,

Hi Tristan
The big issue is that to make the paint go hard you add a hardener and the hardener contains isocyinate which causes lukeimia and other nasty illnesses. When the paint is cured the isocyinate is still there so when you sand the paint it is in the dust. It is a do it at your own risk. Wear safety glasses as the isocyinate is asorbed through your eyes. I would also wear rubber gloves a good quality respirator and disposable overalls. Wet sanding would also be better as you can hose the residue away. PUP is very nasty stuff.

Thanks for that Rod!!
I can acquire myself a half face fitted respirator, mono goggles and disposable overalls so I'll do that if I decide to work with it.

But what's the good side of this super nasty paint? And would your re-spray your car with it?

Thanks,

matt finish and its exceedingly durable if you put it on right.

wet sanding is your first line of defence avoid power tools if you can and chipping off is better than sanding or grinding off old paint.

No, I woulnt respray with it, touch up yes but not a comlete respray. If I was paying for it and there wasnt going to be a health loading on the labour then Id hae it sprayed on.

The aircraft paint is similar. Paint gear is sealed plastic overalls, gloves, footgear, full head mask with external air supply etc. The thought is that without all this the paint job will last longer than you will.

Thanks for that!! As I've been told your the expert, what would you recommend to respray it with?

And is it safe to say the ADF use it purely because of its durability qualities?

The paint is a chemical agent resistant coating, it can be washed down to decontaminate. It does not fade and go powdery as quickly as other mat finish camo paints. You can get spray cans for touch up work.

The reason that there are stickers everywhere warning you about PUP is to prevent litigants claiming that they did not know the vehicle was painted with a product that can be hazardous. The same reason that requires warnings that the vehicle may have asbestos. Etc.
