Re: [Phys-l] UV-curable epoxies?

Dentists now use vis. curable, as, perhaps?, they don't want to be sued for causing melanoma.

I doubt if their cements are clear.

To get rid of bubbles you need to put it in a vacuum chamber and slowly evacuate for a few minutes.

In the old days (when not outsourced) dentists used centrifugal casting. One wound it up as a victrola.

bc's host in Moscow had a centrifugal espresso maker!!!

p.s. I suspect methacrylate monomer would do the job -- this may be what dentists use(d).

You may well find that many clear epoxies are 'UV curable' whether
sold as such or not.
We found quite by accident that a thin layer of stycast coated on
paper would be cured by the exposure given by a Xerox machine.

And my wife was quite taken aback by how fast her fiberglas+resin
repair on her horse trailer would setup in full sunlight.

Hi, all,

A colleague and I are thinking of freezing some particle dispersion patterns
in epoxy, but we need something that's relatively optically clear once cured,
isn't TOO expensive, isn't super-viscous until it's cured, and can be obtained
in volumes that aren't microscopic. Does anyone on this list have experience
with UV-cured epoxies, and can recommend for/against any particular ones? I may
have to ask my local dentist, too.
