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?

This post has exactly zero relevance to my professional career or personal projects, and this is exactly the type of esoteric content I love about HN!

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 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.

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?

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.
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.

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.

Huh. So it's a stronger, harder, less brittle, clear wood glue you can dissolve with acetone. Neat!

How does its strength compare to MMA structural adhesives? What materials is it compatible with?

Am I the only one that read it as Polaroid ;) ?

Polaroid for B-72 bomber

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.

acetone will dissolve it, dunno about turpentine.
