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?
- halestock 6mo agoI found a couple: https://resources.culturalheritage.org/osg-postprints/wp-content/uploads/sites/8/2021/11/osg025-001.pdf https://resources.culturalheritage.org/osg-postprints/wp-con... https://www.zoicpaleotech.com/pages/paraloid-b72-in-fossil-preparation https://www.zoicpaleotech.com/pages/paraloid-b72-in-fossil-p... acetone will dissolve it, dunno about turpentine.
- boppo1 6mo agoI'm reading that turp does not dissolve it, which is ideal so I can mix paint on top of it.
- chromacity 6mo agoIt'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.
- boppo1 6mo agoDoes it not level from gravity like other resins?
- chromacity 6mo agoIt's solvent-based, so it won't set well in thick layers and it will shrink significantly as the solvent evaporates. You can do thick layers with solvent-free thermoset resins such as epoxy, but epoxy will yellow over time.
- greygood 6mo agoPurchase as crystals and dissolve in acetone or ethanol to desired concentration. It will self level based concentration, allow to evaporate before applying next layer
