Polyurethane does not cure ? where to buy other liquid rubber ?
Last month i bought a gallon of Polyurethane paint, which consists over 75% PU, and around 25% is a solvent which evaporates easily, but my PU never
cure, it is always a liquid ? even when i tried adding some epoxy or epoxy hardeners or any other glue it is still a liquid ?
Any ideas why ?
Also where can i find Polybutadiene ?
And there are lithium-Catalysted Polybutadiene, whats the lithium compound they use for the catalyst ?
thanks.

i believe you mean harden, for future references..
that seems weird.. have you tried smearing it on some surface and seeing if it dries like that? it could be if youre trying to make some composition
with this that it gets blocked in by itself and just cant escape.. spread it out while drying?

Isocyanates are usually used to initiate cross linking. Most are very moisture sensitive, and very toxic materials.

Sorry, I just re-read the original post.
Is the material meant to be used straight out of the container or does it need to be mixed with a second component?

That is what i am unsure of, i tried it alone, and added epoxy, both wont work, i guess I will just buy some Polybutadiene next time.
