Default Various Glue Tests

I did some glue tests and came up with this chart, hope it helps. If anyone feels like I have incorrect data, or suggestions, let me know and I'll redo the test. Sintra is the PVC foam material otherwise known as komacel.

Gorilla for the win...
Thanks for the info, very appreciated.
I have had great results with the Gorilla glue and it's what I prefer to use.
Although I use all above listed products for different applications.
Can't go wrong with all of them in your gluing arsenal.
Thanks Joe

Does Gorilla Glue weld the plastic like the Plastruct stuff does? If so I might have to get some.

I have had consistently terrible results with Testors Cement. Pretty much every time I've used it, it has cracked over time and split cleanly as if it didn't melt the plastic at all. Even stuff I glued when the tube was new has broken. I'm glad I abandoned it and picked up the Plastruct stuff instead, so much better.

It's also worth mentioning that Shoe Goo doesn't completely harden, so it leaves a slightly flexible joint. Good for attaching stuff that might get bumped around, like mirrors.

Superglue wont dissolve the plastic, but it just adheres to it very well, from my understanding of it. For delicate styrene joints, I would still use the Plastruct products.

The only products that actually welds or dissolves the plastic are the 2 Plastruct solvents listed here, and also solvents like Tenax 7r. The others are just glues, and (sometimes) stick to both parts but dont dissolve them together.

I haven't used Testors cement extensively, but from what I have seen it works very well on styrene/styrene bonds. Perhaps over time the joint weakens, but I dont have the data to back this up. If anyone can confirm this, I will change it to a 3 star rating.

the Testors Cement in the tube is not good, use the testors in the bottle , also try MEK

Ive used the testors cement in the metal tube, and it seems to create a permanent bond for me. What is your experience with it? Does it degrade over time?

It seems strong at first, to trick you into thinking it's working, but that's how it gets you. It's deceptive, and dare I say, manipulative. It may be fine for plastic models, but for RC stuff where the bonds are subject to stress from bumps and knocks, it's no good. It does work *slightly* better when doing styrene-styrene bonds, but with anything else it doesn't work at all, including RC4WD ABS as I learned when bobbing the bed of my TF2.

I used it on plastic models for years and the best thing about it was I could take them back apart and rebuild the models when I got better at building,

the glue would degrade and the models would come apart

Styrene to styrene or styrene to ABS you can use Acetone, same stuff that is in MEK, MEK is a bit more pure.

But I want to know what bonds styrene to polycabonate aka Lexan

Try it on some scrap first...
I think you will find the "Gorilla Glue" Supper Glue Works fantastic.
Ive had killer luck with it on every thing.
I use "Hobby Town" activator with it. Cooks it just right. Not to hot.
"Jet" industrial Gel super glue also rocks with it's activator. Expensive though.
It is my next personal choice.

Scuffing the Lexan with sand paper or even a small file also helps,
For very small areas, Try the back of the Hobby knife.. Controlled scrape glue add piece and hit with activator..
I also still use baking soda as an activator and filler..On larger pieces.
Give it a try my friend.

Don't think they sell Gorilla Glue here in Norway, but I DO have Zap Goo and Hudy Body Fix, and I suspect they is basicly made of the same stuff.
Have never tried the Hudy body fix, but it's good after what I've heard

Also found IPS Weld-On #16 plastic glue bonds both styrene and polycabonate.
Nobody sells that stuff in Norway as I'm aware of, and ebay don't quote a shipping cost either..

But I gonna try both the Hudy Body Fix and the Zap Goo and report back later this week (y)

MEK is methyl ethyl ketone CH3C(O)CH2CH3
Acetone is ketone (CH3)2CO

Different chemicals all together, but they have similar solvent properties. There is some overlap to what they dissolve, but there are some things that one will do that the other does not. Clear plumbers pvc solvent contains MEK and works very well on some plastics.


Try this for polycarbonate Loctite® Epoxy Plastic Bonder. I've used it for lexan to PVC and for ABS. It might work on styrene, but I'm not claiming it does.

Thanks for the heads up

MEK is not sold in my town, have to order online if I gonna use that.
Have so far used acetone to bond styrene to styrene, and works good.
MEK might be even better

Great tip on the Loctite Epoxy Plastic Bonder.
On Henkel-Loctite guide they state "Polystyrene is compatible with acrylic adhesives" and on the Loctite Epoxy Plastic Bonder page it says "Bonding substrates such as: PVC, polycarbonate, acrylic, ABS" etc etc.

So yes that seems to bond styrene and polycarbonate

Now to find a place around here who sells that Loctite....


Btw: Tested the hudy body fix on a scrap piece of lexan and styrene.
After about 2 hours I could easily rip those apart.
So no good then...

In the end I used adhesive contact glue to bond the styrene to polycabonate, as this was the thing that stuck best to those bits, and are available at lot of shops around here..

Mine is from Pattex and are VERY strong
