What type of resin has the lowest shrinkage ratio?

[Anakin Starkiller]

Hey guys. I need to cast something in resin and produce little to no descrenable shinkage. Can anyone recomend a good low shinkage resin or no shinkage resin? Thanks

Not sure. I used the Smooth-cast 320 and it said .01

The 321 and 322 were .007

I would think the resin that takes longer to kick would have the least shrinkage.

You want to ask the resin vendors about this. Ask them to recommend a formulation and perhaps fill for your application. That's the direction my research took when I was looking into this sort of thing. LOTS of options out there.

Super low or no shrink pourable urethanes are out there. The good ones that don't shrink are really expensive.

I use Sil-Plastic from SilPak almost exclusively and I think it's shrinkage is in the thousandths of an inch. It's very good stuff, and is about the "high end" of mid-priced.
