Using super sculpey III to sample small things

Super sculpey is an item found in most large US craft stores, such as Michael's and Hobby Lobby. It is a non sticky one-part clay that requires baking at 130 C / 275 F to harden. It is inexpensive - abuot $2 USD for 60 grams / 2 ounces.

A small pinch can be squooshed onto a detail, like a tiny eagle crest, carefully peeled off, then baked.

The nice thing is that resin doesn't seem to stick to the sculpey, allowing the pattern to be regenerated.

Alternatively, if the original pattern is a high temperature alloy (such as GW's), the entire pattern + sculpey can be baked together. The hardened sculpey is then removed. This technique prevents distortion caused by peeling soft sculpey from the pattern.

This technique is precedented in White Dwarf and Block Gobbo publications. The cited documents used green stuff.

I've not tried Sculpey III, but I have used Super Sculpey and Premo for this. I've baked metal with the clay pressed on, and I've baked polyurethane resin as well - so far I've had no problems with distortion or melting at all. That's at 130 degrees C - is Sculpey III baked at a higher temparature?

Regards,
Reaver

SS III is at 130 C as well.

Who manufactures using polyurethane resin?

Well, I do!

And I kinda thought everyone else did too... I mean polyester resin's horrible, smelly brittle stuff! What did you use for your Imperators?

A variety of resins, most only slightly stinky. The stuff from Smooth-On is called "liquid plastic" and the ingredients list is stuff like "TSR18329440-Z".

Not being versed in advanced chemistry, I don't really know what sort of resin, or plastic, it is.

I know that I do love Smooth-On company, though. Better, faster, friendlier service than Micromark.

I'm pretty sure all Smooth-on resin is polyurethane, as is Por-a-kast and FastCast. Last time I checked, ForgeWorld were using polyurethane as well.
Easy check: if the resin you used was mixed in equal quantities, it was almost certainly polyurethane. Polyester resins are usually one part, to which you add 5% hardener. And they stink up your house for days!

Along the lines of this topic, I have tried two-part silicon putty from Smooth-On.

It doesn't work well for the very small applications I want it for - too much 'rebound'. But at least it doesn't have to be baked.
