Polycarbonate
Hi all,
I have heard tell that, that there can be issues when applying vinyl to polycarbonate. Apparently the polycarb is prone to out gassing and can therefore create bubbles under the vinyl. My question is, is this a real issue and is there any thing else I need to consider. I have 100, 1000mmx1200mm reverse printed flood coated signs to make so would appreciate any comments.
Thanks

Martin, I have applied to polycarbe on a few occasions and not really noticed a problem but the signs were up pretty high so you probably wouldn’t have noticed if there had been bubbles.
At this sort of quantity would you not be better having them screenprinted though? -
Years ago I made a lot of reverse p/carb signs for a multi-storey car park – all reverse applied. Never had a problem with out-gassing.
1/2 of them were reverse applied / clear, but the big ‘pay & display’ signs were reverse applied text & print (& then back-sprayed in white – gives result that looks like screen print) & white vinyl overlaid – still look as good today as when they were done…no bubbles or deterioration.

I have done a little bit of polycarb, never had gassing issues recently though.
I know it was a problem in the early days, but new technology and manufacturing these days, I’ve not heard of it as an issue for years

Hi Martin,
I have come across this once when producing some internally illuminated menu faces. After some experimenting we found that using a better quality vinyl, 5-7 year, took care of the problem
It was quite a few years ago and we put in down to the polycarb, economy vinyl and heat from the slimline case to the face.
Most of the vinyl today is a lot better quality anyway.Mike
