## Description

"UHU por wurde speziell für die Verklebung von Polystyrol-Hartschaum (z.B. Styropor) entwickelt. Dabei bietet UHU por eine ausgezeichnete Verklebung von Teilen aus Hartschaum untereinander aber auch mit anderen Materilaien. Speziell auf Kunststoffe ausgerichtet greift der Kleber die Oberflächen nicht an und bildet einen dennoch flexiblen und alterungsbeständigen Klebefilm. Die nahezu transparenten Eigenschaften nach dem Aushärten erlauben auch das Verkleben an sichtbaren Stellen ohne optische Beeinträchtigungen. Neben der Verklebung von Polystyrol-Hartschaum (z.B. Styropor) miteinander lassen sich Hartschaum-Werkstoffe mit UHU por auch mit Holz, Holzwerkstoffen, Metallen, vielen Kunststoffen, Textilien, Papier und Pappe verkleben. Auch Fotopapiere oder kunststoffbeschichtete Colorpapiere können mit dem Spezialkleber verklebt werden. Nach der Durchtrocknung entsteht ein neutraler, säurefreier, alkalifreier und transparenter Klebefilm, der vor allem auch mit seinen wasserfesten und alterungsbeständigen Eigenschaften überzeugt. Die sichere und feste Verklebung schwieriger Materialien wie Polystyrol-Hartschaum (z.B. Styropor) untereinander und mit andern Werkstoffen zeichnet die spezielle Ausrichtung des Klebers aus.

Review: Facile da usare molto efficace e veloce, non credevo fosse cosi rapida e che la tenuta fosse cosi sicura. Un ottimo prodotto.
Review: 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.

## Questions & Answers

**Q: Is this from China**
A: Copied from the corporate web page.. "Since 1994, UHU has been a 100-percent subsidiary of the Bolton Group and a Bolton Adhesives brand.  The majority of our products are manufactured in Germany and the Netherlands."

**Q: I need to glue styrofoam to the inside of a terracotta pot - would this work? I have fake flowers in the styrofoam and need it to stick to the pot.**
A: It should work good. It hasn't melted the styrofoam for me and sticks to most things

**Q: Is this thin enough to be drawn into syringe 4 injection into drilled holes in fiberglass roof skin delaminating fr underlying luan/Styrofoam seams?**
A: Probably if you work quickly

**Q: Will this hold glass to Styrofoam  and is it resistant to slightly damp conditions?**
A: I used it to glue artificial turf to florist styrofoam to make a graveyard for "Children of the Corndogs" for Halloween. It worked really well. You apply glue to both surfaces and wait 10 minutes before pressing them together.

*by A***Y on 11 April 2018*

Yep, it is UHU Por - the genuine article, and I got it at a good price. For some reason, this glue isn't all that easy to find. I've only ever been able to buy it online. This is the best glue for styrofoam aka EPS (Expanded Polystyrene foam) - it won't dissolve it, like some. It's popular for aeromodelling, but it sticks most things to most other things. I've used it with wood. I've even stuck bits of cork and felt to brass and woodwind instruments with it. It can be used as a contact cement - apply to both sides, wait a few mins, then press together - or it can just be used wet, with a bit more setting time. I prefer to do that, because you get time to reposition things. The smell isn't unpleasant, and I think it's reasonably safe for kids to use, if that's an issue. It sets as a clear gum, not hard or brittle. You can generally get things you've glued with it apart again, if you really try.
