LCE Persex Adhesive

[maxi-model]

Give these people a go http://www.starloc.eu < Link To www.starloc.eu . Found them at the Midland Model Engineering Exhibition a couple of months ago. They seem to have adhesives for every occaision. Especially various plastics applications. Given that must plastics adhesives are solvent based then getting away without marks is going to require care. How will the windoow be fitted ? Flush or on the surface ?

If you are still not sure why not try thin strips of heavy duty double sided clear tape and use that to fix the perspex on, assuming you are fixing from the inside and not needing a flush fit. If flush fitting, try Microscale Kristal Klear. It is a PVA type glue that will not attack plastics and can be wiped off. Thin it down with water 50/50 and let good old capilary action take over and flow it into the gap betwixed window and body.

I use both metods depending on the situation.

Good old hot glue gun. It doesn't actually react with or mark the plastic and you can carefully peel/scrape away any excess.

I have just re-read your initial post. Am I right in thinking that you intend to "laminate" the clear oversize sheet of perspex with the "smoked" perspex windows, that have been cut to size to fit the appatures, so as to acheive a flush fitting effect ? If so your safest bet would be the kristal Klear method I mentioned and ditch the oversize backing sheet of perspex.

You could do it with a proper solvent designed for use with acrylics/perspex, flooded onto the surface where the two window parts are to be laminated (butt jointed) and clamped together until the solvent has dried . Personally I would leave that to a specialist company or someone who ha done this before. It's a standard technique for larger (e.g. shop display) clear perspex fabrications.

In the old days ether was used!!
However, there is a specific adhesive for Perspex. Note..Perspex is a trade name and not all clear is Perspex. So, what may stick one will not stick another.
Perspex name, is like calling all vacuum cleaners Hoover.

The generic name is Acrylic, comes in sheet, dowel and just about any (extruded ?) section form. Can be clear or opaque. Same acrylic glue/solvent works on Perspex (ICI trade name I think) as they are all the same thing. Any plastics specialist will know what you are after.
Not to be confused with cheaper Polystyrene sheet, etc', that some Bigco. DIY store my try to fob you off with not realising it is not the same thing.

Not forgetting confusing ABS, Polycarbonate ........................................................... that's another story.
