Glue Help

[Tony]

This might be just for ChrisH, although someone else might have a good idea.

I have some decals that are vinyl mounted onto perspex - I have a load of them, but one set is causing me a problem!

These are located above a TV which obviously gives out heat, and because of that, these things are peeling.

I have stuck them back down, and i have used a couple of types of glue in the past which I can't remember the type of but has failed anyways.

any ideas to what the best glue is to do these? I thought of superglue, but was worried about the perspex/vinyl combo and whether it would affect them.

There's a pic attached to show what I mean.

TIA

I'd have thought acrylic/plastic glue or a contact adhesive would be best.

Yeah, you do need help. Your Blockbusters obsession is getting out of hand.

Sorry for the delay temps, missed this!

Vinyl contains pthalates which makes it flexible. These pthalates can migrate into the adhesive causing it to soften. Think back to vinyl tape on electrical wiring under a car bonnet going all 'greasy'. Plasticisation.

Beware of solvent based adhesives as these are likely to crack/knacker your perspex. Liquid adhesives are also likely to be messy.

Given that these are decals I think you'll need a permanently tacky pressure sensitive adhesive transfer tape, quite thin and resistant to plasticisation. You'll need to remove the decals and apply the tape to the rear. I have shed loads so if you want any just let me know.

Cheers Chris, and thanks for the offer of the tape,I did think about using some tape but the trouble is it would show through as they have oblique lighting on them and led lights behind them.

Thinking of getting them remade using different material and have someone working on a quote for me.

It is quite a high profile area do needs to be proper as you can see in the pic

This adhesive transfer tape is clear. 

[Tony]

Yeah, but it's profile of it you'll see through the vinyl

Unless it's a big sheet thingy?
