Glue Recommendation

[jackdoud]

I'm working on a project with a friend and idea has come up but it'd require gluing sheet styrene to high density foam insulation. I've worked with both individually before but have never tried glueing the 2 together other than some small scale stuff. The problem as I see it is, glues that are good for styrene melt foam and glues that are good for foam won't secure the styrene. We're basically looking to coat the foam with a skin of styrene. I was thinking mabey Liquid Nails or Goop could work but I don't have much experience with them. Anyone have any recommendations?

CA glue, applied in a thin web-like grid. Leave alone for a day. Get the gel at Hobby Lobby or Michaels.

It glues anything... especially skin.

Hot glue gun?

Been using contact adhesive to bond sheet styrene to high density urethane foam for years. Apply three coats to each side and it should never come loose.

Most CA glues I've used melt foam, do you know a specific brand? There's a large number of peices to do, (it's basically an armor costume) so small bottles of glue would get tedious.

Hot glue's got some problems. Some parts have a large area so by the time I cover the whole thing some of it will have hardened. Also, low temp glues often don't bond to styrene well and high temp ones melt the foam.

Try the gel. It sits up on the material. If it melts while gluing, it may improve the fusing of the items. I get CA from Hobby Lobby.

Good luck.

Contact cement. But make sure its the water based type as the solvent based will attack the styrene if its thinner than .060.

I've used POR adhesive to join styrene to expanded polystyrene, foam, depron, metal, wood, acrylic sheet, paper, card, my fingers, urethane resin, selotape, latex - it's excellent. Doesn't damage anything, doesn't melt anything, is exceptionally sticky, takes a while to set though.

No idea if you can get it in the US - it's probably called "UHU Creative for foam" in the USA

 

[minieffects]

No I dont think that brand sells in the us, but Im sure there is a us equivilent. What is its base? sovent or water? is it an epoxy or aliphatic resin?

Unfortunately it's a UHU Germany product, http://www.uhu.de/_uk/indexx.html the pack and all instructions are in German.

It's solvent based and they recommend use as a contact adhesive, but I use it as a general purpose panacea.

It's not an epoxy, no idea what an aliphatic resin is

That's what I use.

Hi all

Occasionally I stick sheet material to foam, and the best way I have found is epoxy resin. ItÂ’s not a glue as such, but I also make stuff in carbon fibre and Kevlar so use the same laminating resin for sticking plastic sheet and foam together. Takes a few hours to cure, but wonÂ’t melt the foam or the plastic, and sticks like doggy doo doo to your shoe. The only thing to remember is sand the side of the sheet with rough sandpaper first, just to make sure, although epoxy resin tends to stick to most stuff just fine with no prep work. Best resin for this is West epoxy as itÂ’s thicker than most and cures without post heating.

RC Planes is my second hobby and gluing foam/plastic/wood together is second nature.

Do you have a hobbytown near you? http:www.hobbytown.com

There is thin/medium/thick CA glue, that is completely foam safe. The thin stuff wicks into the foam faster but has a thinner bond. Medium and Thick are great. You can buy accelerant as well. Put the CA on one side and the accelerant on the other and put them together and you have an instant bond. I have put together armor for trooping with this stuff and it works better than anything out there.

UHU and POR are awesome as well, you can order it from there.

Let me know if you have any questions.

You can buy UHU and Por from an RC hobby shop online. Just FYI.

I've dabbled in RC planes before (built and crashed one, started a second) and used epoxy to bond balsa to the foam wing core, styrene needs to be seriously roughed up to get it to stick though(atleast with the glues I've used). I don't have a hobbytown near me but I do have 2 good "hobby" stores nearby, I'll check them out this weekend and see what I can find. I'd prefer to pick something up locally over ordering online and paying for shipping, especially when I'm not sure how much I'll need or if it will even work. It's gonna be a few weeks before I get to the point where I'll need a final solution so I have time to experiment. Thanks for the info so far people.

I couldnt agree more. Hobbytown is a national franchise chain, but not as good as your local hobby store, I only recommended that because they seem to be in most major cities and you can find what youre looking for there generally.

Let us know how it goes.
