If it's just styrene I always use superglue.

Superglue gel. Bob Smith industries brand is what I've been using for twenty years plus now! O:) This is in the magenta bottle. Works great! :wink:

By "card" do you mean styrene sheet, or cardboard? If its the
former, I'd use a thin styrene cement, like testors or tamiya.
If its cardboard ( that is, paper ) I'd suggest either contact
cement or some form of white glue.
Superglue has its uses, but unless you've got an absolutely steady
hand, or use jigs, I wouldn't use it for flat panels-too much risk
of mis-alignment, and once its down, its staying there.

I'm guessing by card you mean card-stock/cardboard/paper. Plain old white glue can be used for a lot of work but for quick glue go with a thicker CA. Mercury Adhesives is the best of the CA brands but will probably be a little tough to find in the UK.

I note the OP lists his location as UK, so he's almost certainly talking about sheet styrene. Personally I like to use Testor's liquid cement for this. Just don't use too much on thin sheet. thin superglue would be my second choice, the Bob Smith blue label stuff.

I use CA glue to tack styrene card down around curves. In flat areas, I just use styrene cement.

im am using the paper stuff yes. im a student so its being made from old pizza boxes and a like to save a bit of cash. is white glue similar to PVA (Polyvinyl Acetate). i hadnt even considered this. ive been using super glue for the joints and seams.
thanks

Hi,

Yes what is called white glue in the US is PVA.

But if you're gluing something as thick and big as pizza boxes standard PVA may not be the best solution. I would recommend woodworker's white glue - it's still a type of PVA but it is also a good deal stronger, quicker drying and also dries harder than the PVA you would use for lighter wieght card.

You can get it from any hardware/DIY place and don't be afraid of own-brands (e.g. Homebase, B&Q, etc.) but if you have a Wilkinson's nearby theirs is the cheapest and one of the best.

If you want something REALLY strong, use Cascamite. This is a resin glue which comes as a powder in a tin. Mix with water and glue away. Again, this is readily avaliable at hardware/DIY stores.

As a note - almost all the brands our American colleagues have mentioned here are either unavailable in the UK or only available through the web.

White glue = Elmers' types are ALAPHATIC resin. Polyurethane(Gorilla glue) is a PVA type of glue amalgumation.

Elmer's glue is based on an emulsion of polyvinyl acetate, other white glues can be made from an ALIPHATIC resin, Gorilla is a Polyurethane glue but water-resistant cross-linking PVAs are available.

Thanks Kylwell! That's what I wanted to say. I'm just quoting the bottle label. :|

IIRC, aliphatic means an organic compound w/o benzene rings. Aromatic is a compound with benzene rings. So, by that light, PVA is aliphatic. From a health standpoint, aromatic compounds tend to be more aggressive, requiring protection.

Urethane resin used to be diluted with aromatic solvents, but urethane itself is not aromatic. Recently aliphatics have begun to be used with several resins, urethane included.

Gorilla glue is, according to its MSDS:
Urethane prepolymer (40-50%) + Polymeric MDI (a mixture of 4,4’-Diphenylmethane-diisocyanate,isomers and homologues) (50-60%)
Sheer elegance in its simplicity.

Given Gorilla glues properties it doesn't shock me find out it's got PMDA in it.

Thank you for chiming in with that Chacal! :) I don't know much about glues. :( MY forte is paint. :wink: It's nice to have an actual informed response! :o
