UV curing / activated adhesives, resins etc.
« on: July 13, 2017, 07:37:45 pm »
I was shown some amazing stuff at my club some weeks back. It's by JML, and seems to be the most expensive of its type. It's a tube of stuff that looks like clear glue, but when it comes out it's very manageable like quality model lube oil or perhaps super glue gel. The other end of its applicator though, has a small UV LED and when you shine this on the applied glue / resin that's what cures it. No solvent or odour, just very strong bonding that is benign on nearly all substances you want to stick. The mate who showed it to me first used it in a fashion college where he works (you should see his scratch built O gauge US trains though - superb doesn't cover it!)
Ok, preamble over. Who has tried this stuff? There's a few different ones out there and the JML seems the dearest, c12.99, as opposed to 6.99 for another brand, all seem to be in 5ml tubes with the UV torch at the other end.
Any clues please?

We use UV-curing adhesive at work for bonding glass-to-glass, and steel-to-glass. It's extremely strong stuff!

I can see some uses for it in modelmaking, but they're limited. Unless the item you're bonding is either really small, or transparent, then it's never going to cure properly as the UV light can't get to it. It'll only cure around the edge, the bit in the middle will never cure.

Is it strong enough and compatible with the plastic that Farish and Dapol use ?

From what I can gather I make you right. I have a Minitrix 2-6-2T with a broken chassis base plate, and I hope it might be fixed by offering the parts together and putting a layer of UV glue on top then zapping it.
Also, where phospor-bronze wheel pickups have come away from another model's gear tower, hopefully the same could be done with a layer around where the drillings in the contacts are that locate on the raised plastic. It seems they are secured in the factory by melting some of the plastic moulding to larger than the hole in the pickup sheet.

Thanks, @Only Me. That says I don't need to pay the JML price for some then. That's great.

I bought mine off HOCHADA the TV channel, it's called Bondic. Mine came as two tubes with like oversize hypodermic needle ends plus a small UV LED button cell lamp. Trouble is I bought it a couple of years ago so can't say how much. The only thing I've used it for is repairing a small puncture in a stainless steel sink, which lasted as a temporary repair for at least two years until sink replaced. I applied several layers top and bottom and hardened each layer, seemed to work!

Note: Dentists use a similar product for some fillings.

It's about 12 these days, not the cheapest.
