I'm searching for a resin that has specific properties. Most of what I need can be done with polyurethane...except that it's toxic. I'm searching for one that isn't.
I need the final product to...
...have a Porcelain-like feel (rather than a plastic one)
...be similarly durable (or moreso)
...be sandable
...have a white color
...but can be optionally colored
...be good for painting on
...be cold-casted with a two-part mold
...be non-toxic (at least once finished)
I can find lots of kinds that fill SOME of these, but I'd like all of them.
Anyone have any recommendations? Or can point me in the right direction?
