Could this be used to 3D print supports ? For now, the only thermoplastic I know of that can be used to this effect is HIPS in conjunction with d-limonene.
I followed the link to flexographic ink, and now I'm wondering whether boutique fine art flexography could or should exist. Like lithography, but more plastic.
It's a relatively soft plastic and I don't think you can realistically build a uniform, good-looking layer that's 1/8" thick, if that's what you mean. If you need that thickness, high hardness, and nice appearance, I think your best bet is just a sheet of glass or acrylic on top.
It can be used as protective varnish, but that would be a very thin layer, probably 0.1 mm or something like that.

This is the most esoteric post I've seen on HN in a while.
How many museum curators who need non-yellowing flexible thermoplastic are there on here?
Oil painter here, this is news to me and if it doesn't dissolve in gamsol this is EXACTLY what I've been looking for for about 2 years.

I use paraloid all the time, a bit surprised to see it posted here but I’ll support it.
I'm new to it and having trouble finding guides:
- how do I apply it as a coating? I want it to be ~ 1/6" to 1/8" thick and as hard as possible
- will turpentine dissolve or soften it?

Does it not level from gravity like other resins?
I found a couple:

acetone will dissolve it, dunno about turpentine.
I'm reading that turp does not dissolve it, which is ideal so I can mix paint on top of it.
I've done some DIY piano maintenance and I saw what was presumably this available to firm up the hammers. My piano needs them softened, though.
They should make non-yellowing transparent phone cases out of this stuff.
Heh, I upvoted this a few days ago and it must've gotten on the second-chance queue.
Links to obsure but interesting Wikipedia articles are some of my favorite HN posts.
How does its strength compare to MMA structural adhesives? What materials is it compatible with?
Huh. So it's a stronger, harder, less brittle, clear wood glue you can dissolve with acetone. Neat!
Am I the only one that read it as Polaroid ;) ?
No,you are not. I was expecting it to be a camera.
I thought it was a cross between a camera and a bomber.
Edwin Land, the inventor of the Polaroid, worked on the U2's camera.
