UHU Model-Making Glue (Special) Por 40 g 10.8 x 14 x 7.6 cm Transparent

Ok, so I've been a fan of Beacon's Foam Tac for a long time. That stuff is pretty good - this stuff is better. In fact, both work well for gluing but I can use half a tube of UHU POR and store it for 6 months and it'll still be good to go when I open it again. The Foam Tac stuff starts to go bad after you open it - so use it all in a single build, or lose it if you store it for a while. This is the better glue just from a storage perspective. As for adhesive properties, honestly, this might be just a TAD bit better than Foam Tac.

Use it to build radio controlled model airplanes out of foam board and foam insulation from big box. Produces a strong joint. It says on the box to apply adhesive, touch pieces together, pull them apart and then wait for 10 minutes or so before making the final join. Have found that waiting only a minute or so is all that's required to give a good initial "grab," but I don't stress the joint for another 30 minutes or so. It is easy to apply and with reasonable care the tip of the tube does not make a mess when you put the cap back on. It's a good replacement for the glue seen on Youtube that is not available in the US. It's good stuff!

Works. Clear. This glue does its job well. In a tube that does not dry up as so many others do.

I've used it on the hard styrofoam used in radio-controlled aircraft. The glue does its job. Takes a bit of getting used to, and, since it's made in Germany, the instructions are in German with the exception of a sentence saying to spread the glue, wait for it to dry, and press the parts together. I'm not sure it's any better than Welder's or Foam-Tac, but I wanted to give it a try.

My goto adhesive to fix my foamy rc airplanes and general gluing. Get this.

I needed to glue a wig and a fake beard to a painted styrofoam wig head. THIS IS THE STUFF! It was pretty easy to apply (hey, it's glue... be smart... work on a surface you can scrape or throw away, and either wear gloves or prepare to be sticky). It dried in the time described, and held perfectly for the performance (and beyond - this is a prop I'll be using over and over for hopefully years). I tried an endless number of other things and this is the winner! Have to remember this!

The "Por" version works very well with XPS foam. At normal room temperature, I target about 5 minutes of open time before joining the pieces, else ~ 1 minute if I want to slide the pieces (slightly) into place. When sanding a dried joint, any excess glue does tend to clump and usually has to be removed by hand, which is rather tricky. Before discovering Por, I used epoxy. Sanding such a joint was problematic because the epoxy is much more abrasion-resistant.

Exactly as advertised and quickly shipped, in a box, so no damage. Nice.
