Gluing perspex

[mick]

I need to stick narrow strips of perspex to sheets of same (washboards, you know). What is the best adhesive to use?

Chloroform ? (spelling) isnt it? with small particles of perspex disolved in it. Or give Dorking plastics, in Dorking, surrey, a ring they will tell you.

Always thought Methylethylketone was the stuff to use. I know a lot of the sign makers use it for purspex signs. Or even polypipe adhesive works

You need tensol this can be obtained from most acrylic suppliers, you need external stuff.

I used to build underwater camera housings from Perspex and the best stuff was called Tensol No 7. It was a 2-part glue consisting of methyl methacrylate and benzoyl peroxide catalyst.

I haven't bought any for a few years now so the name may have changed but Plastics stockists will know. I use Amari Plastics PLC ( www.amariplastics.com ).
They have a place at Hedge End close to the centre of the boating world!

Superglue woks very well.
Make sure that you put just enough on to cover all the area or it does not give a clear finish and looks disappointing, but not enough to "float" the part away.

Tensol works ok but is not easy to use, liquid solvent cement is better. Put your 2 smooth surfaces together and run the glue along the edge. The glue is pulled into the gap by capillary action and is very strong, clear and very easy to use.

Theres a two part glue used buy upvc window fitters called sfx , it dries a sort of smokey clear . Apply the glue spray the activator and its stuck in seconds.Youll get it from most builders merchants . Also known as mitre mate .

A follow on from my post, I suggest that you use adheasive recommended by maunfactures, as some tensol will degrade in uv light the 2 part T7 is what we use for external signs, check with supplier! are you using Perspex! cast or extruded! or another make! or polycarb!

This is superglue, (cyanoacrylate glue) with a separate accelerator which sets it instantly. If I was going to use superglue for this job, I'd use low viscosity, or thin superglue. Hold the two parts to be joined in place and then carefully apply the glue at the interface. Capillary action will take the glue into the joint and the thin cyano goes off very fast. Good model shops sell thin cyano, as it is used for model aeroplane construtcion. Buy some teflon capillary tubing at the same time, and use this to make an applicator spout for the glue - you will get much better control over the application of the glue to the joint with this.

You can make your own accelerator - dissolve some sodium bicarbonate in water and apply with a hand spray (an old Mr Muscle spray works well). This is more benign than the organic amine which the commercial accelerators use.

I normally use Tensol 12, which is a one-part adhesive but almost as good as Tensol 7. To mix two-part adhesives you either need accurate weighing equipment or need to make up a large batch at one time.

yes, it`s too much information.....Well here is another solvent that can be mixed with perspex shavings to make a solvent glue that will give a chemical bond ie. weld it,Tricoetheline; or as it was known in thoes brass fire extinguishers that you pomped, before the fumes were considered harmfull CTC. and I suspect readily available.
