Hi everyone,

I have an unusual question. To me it's a science. UV Bonding. I'm thinking about gluing 4 stainless steel legs to a piece of glass. There is very little info on the net. The glue apparently requires UV light with a certain wavelength.

Some UV glass glues can be cured with just light. How does it work?

Say if a certain glue requires 400 nm wavelength to be cured properly, what will 500 nm light do?

This glue does not require UV light, but direct sun will do.

Any ideas?

I u.v bond quiet ofter, glass to glass that is. If you can wait till tomorrow i can give you all the info you need regarding glue and lighting.

Yes please. I also have a small UV 8W light. No idea what its wavelength is.
 
we tried this at work and it didnt work very well. We had the full UV set up for bonding glass to glass and glass to mirrors. We tried bonding a toughened glass shelf onto metal pillars. In the end we went with holes in the shelf and the pillars tapped out.
 
you could try it, but for commercial use we couldnt risk the bond failing. And they didnt want to be able to see a big lump of glue under the glass. Maybe this glue is better, take a risk and try it :)
 
You'll need quite a large surface area of contact where there is little risk of high levering forces in order to prevent the legs from coming off the glass when moving the table around. The shorter the legs, the better.

I've performed a fair bit of mechanical testing on a fair few UV curing adhesives in the past, and have to say that most of them take longer to cure than the manufacturer specifies, even with their recommended light source. They vary wildly in strength too, even those specific to glass to metal 'structural' bonding.

Do you reckon I should get this done by some glass specialists?

This Nano470 glue doesn require UV light, but just a normal light. The guy on several videos was showing the strength of the glue and from what I could see, the glue was very very strong. Enough for my table/pc desk :P

This is just a plate http://www.hafele.co.uk/Hafele35a1/...6021&ig_id=20992&title=Glass+top+fixing+plate (just an example as the price is a rip off, I can get these for about £2 each :P ) these are specially made for glass bonding
and these are the whole legs: http://www.eepl.co.uk/60mm-stainless-steel-table-legs--uv-bonding-to-glass-f14-g79-c2768 also for bonding

These tequire holes in the glass http://www.eepl.co.uk/60mm-stainless-steel-table-legs--through-glass-fixing-f14-g79-c2767 but I want to avoid holes.

I'd definitely tell a glazing specialist what you're intending to do. They should be able to recommend the materials you'll need and advise you. Toughened glass can be very expensive too, and being a PC desk I imagine you'll need quite a hefty piece.

Yes I'm waiting for the price. They guy will ring me back tomorrow. I ordered 1350x750x15mm toughened piece of glass... Before I ordered 1800x350x12mm toughened glass from them and it was £140 and comparing to my local glass shops it was £60 cheaper. I wouldn't expect this to be more than £200...

I just want a simplest looking piece of glass with four legs cut to my size... i know it sounds ridiculously expensive :mad:

In the end I've managed to bond them legs to that glass without any fiddling with any professional equipment.
Looks like any UV light will do, but may take a few seconds longer to cure. I used Philips fluorescent tube, 8W UV/BLB T5 30cm.

Is that an led strip affixed to the back edge of the glass, and if so, do you have any more pics of how it looks under different conditions (daylight / artificial / no light)?

This is during the day, and yes this is a cool white led strip attached to the back edge. This cool white looks green through a 75cm deep glass.

Here's a blue led strip from ikea under my tv, same glass thickness, but is only 35cm deep:
