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.

		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.
