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

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!

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.

I use lots of different glues for various applications. This glue is very useful. It is so far the only glue I have found that doesn’t dissolve styrofoam and it retains some elasticity after it dries rather than get rock hard. That is very useful.

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.

Works better than I was expecting. Saw a video that someone recommended this, so I gave it a try. My new go to foam glue.

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!

I’ve been using this stuff for years, love it!

If you thought "Foam products" was styrofoam, you will be horribly surprised to find out it will eat straight through it. DO NOT BUY if using on "Foam products". You will absolutely regret it
