Ok guys, I am having some trouble with this one...
With my lasers, I am doing mirror alignement, and I want to glue the mirrors down (as mounts are big and have a tendency to walk over time)
So, I need some glue that will harden rock hard, and harden when I want it to. Unles someone has a great alternative, I am thinking UV cure is the way to go, especually considering that I already have a uv source for curing epoxy
In any case, I have searched through a few manufactures site, but invariably they all have their catalog hidden behind a ton of useless catagories, so I couldn't really find anything that was being marked as 'cures rock solid' and couldn't find anything with a datasheet that had any value that seemed relevant.
In any case, I was wondering if any of you guys know where I can get a small (100c syringe would probably last me well past the expiration date) amount of really hard uv cure epoxy?
Also, I need it to shrink as little as possible as it cures, the stuff I had was like 3% shrinkage, so it walked the beam as it cured. I can account for that (cure both sides at once should do for now) but I mainly need it to be stable after it cures.
I know the stuff exists, most commercial lasers are made using it...

The stuff on ebay is not what I am looking for, if I knew the correct product to be using from a large company (loctite?) I could probably get it from mcmaster.

hmm, the only Acrifix I could find is a solvent weld glue for plexiglass, which I don't think would work too well for holding a glass optic to an aluminum mount (especially considering that the packaging materials are listed as glass/aluminum)

yikes, that is a little out of my price range. Maybe I should wait till I go back to Ortel and beg them for some I know they use that kind of stuff by the gallon (and throw 1/2 of it away when it expires)
But for the next 3 months, I wonder if I could DIY it? Like take the normal cheep stuff and mix it with some fine powder of some sort? glass microshperes? Or aluminum powder? Talcum powder?
