can i bond glass to aluminium tray?
Anyone ever done any work with glass? We have a customer who wants a coloured glass fascia but with no frame or fixings showing. The only way we could think of doing this was bonding glass to the face of an ali tray but wondered if anything like this has ever been attempted before?

how will the sign be lettered?
is this sign illuminated?
why glass?
why no frame?
has he seen anything similar that hes trying to replicate? -
No letters on it, just a plain fascia in a specific RAL colour. Has to be glass or acrylic (that’s the ‘look’ the want) but no fixings showing at all! lord knows why but that’s what they want.

So im not getting this wrong… the fascia is blank. just a colour tinted sheet of glass, or the background is a colour with clear glass?

Look towards the car industry, windscreens have been bonded to metal for years without additional mechanical fixings.
Is the glass opaque or translucent? if its the former, concider having the glass supplied with dowel holes (not all the way through though) that will locate on pegs fitted to your ally tray. The dowels will take the weight and the adhesive will hold the glass to the tray. Top tip with adhesive…….its surface area in contact that gives strength.
Loctite do small tubes (£5 ish for about a toothpaste sized tube!!! not cheap), but have a chat with a local windscreen fitter…….

Yes just a blank fascia. This is either side of the main signage. It’s like an alcove and they want this glass flush with it with no visible fixings.

Hi Graeme, that is exactly what we have thought of doing so far. I’m just concerned that the adhesive will be enough to hold the weight of the glass (probaby about 2m x 0.5m) It’s not something we’ve done before.

ok, this is a guess… but are we talking like the traditional look pub signs that have reverse gold leaf lettering on the middle panel and the rest of panels are glass?
if you are bonding glass to a panel you will need to flood it in a liquid adhesive. i.e. dibond panel below, covered in a liquid adhesive and glass sat on top. the trouble with this sort of lamination is little air bubbles. you have to know what your are doing or stand the chance of air trapped.
this happens when opal perspex is bonded to another layer of perspex then illuminated. anywhere the adhesive hasn’t got to there is a visible shade/colour difference.i work with glass on glass at times. this is crystal cut glass and no adhesive is visible at all… its cured using UV light and requires a flooding process like i suggested above. I am probably wrong in what i have said above because i cannot imagine this to be the process of creating a sign unless the customer is willing to pay for his vision/idea?

Does it have to be glass? I would have thought that a translucent acrylic would probably do just as good a job and will probably be easier to fix and lighter as well, lots of colours available as well.
