These two cans were at the very back of an old worn out, rat infested warehouse since the 50s and then they decided to sell this to somebody who used them as a soccer ball. They returned them and then I was lucky and bought them..Besides that the product has a bunch of holes in the container but still works petty good. Cure time is definitely 2 minutes . And then it's solid rock... disappointed that I paid 40 bucks for damaged product that has dirt and grime and impurities up the a**. But it worked..Would I buy again... I guess...

WARNING! YOU DO NOT NAVE 2 MINUTES TO GET THIS OUT OF THE MIXING CONTAINER IT GOES OFF @ 1:30, when I say goes off I mean its done, rock hard! The cans did not have equal amounts! I will be going back to lets resin!

Will buy again

Good material. Works pretty fast but he sure that you mixed it well. Better to use scales and add a bit more of part B than mentioned in the instructions.Awful package. Keep wipes or paper towels next to the mixing area.

If you get lucky with dump and stir it works well enough.

The box indicates that the material hardens in 15 minutes, but this is completely inaccurate! After mixing components A and B, not even 2 minutes passed, and during pouring into the mold, the composition unexpectedly and instantly changed from transparent to white and solidified. This reaction indeed occurred within a second. I not only spent 40 dollars but also, due to the extreme hardness of this substance, my mold was damaged. I deeply regret the time spent on making the mold. I am shocked by this product! I believe it would be entirely fair if the seller of this item refunds my expenses.

If you're a casual hobbyist tinkerer like myself, you're probably more familiar with epoxy resin than polyurethane. This was my first experience with polyurethane resin, and I'm impressed, though it's not a 1:1 substitute for epoxy.- This is very quick curing resin; the containers say that it takes 15 minutes to cure, and it was mostly hardened and unworkable in three minutes. This is good and bad, depending on your use!- It's much less viscous than most two part resins, and flows very quickly. Again, this could be good or bad. While you can't lay on thick coats, it flows into intricate parts and levels quickly, and especially for casting, as it recommends, this is a good thing.- Because it's less viscous, it doesn't trap bubbles very much - none that I could see in a couple small tests. Excellent.- It's not as hard as epoxy resin. It's still plenty hard for most purposes, but it feels like a high quality plastic instead of a nearly glassy finish.- It cures white, not transparent. This is a big one that disqualifies polyurethane resin from replacing epoxy resin in a lot of cases. However, for casting, or making something paintable, this doesn't matter.- It gets hot. Since it cures so quickly, it lets off a surprising amount of heat for a few minutes, and more the larger the mold. 20 ml was probably about 110 F after a couple minutes, then subsided.- The bottles are a little odd. It wasn't very convenient to pour them without spilling a few drops, and the caps don't feel especially strong.- It's fairly forgiving on the ratios. I've worked with resins before that stay tacky indefinitely if the ratios are ever so slightly off. I deliberately mixed a slightly imperfect batch closer to 1:1.1, and it hardened up with no issue.All of these make it very easy to work with, and I'm happy with the product, just know the differences getting into it!
