Alternative Casting Material for Resin

[Roger Reutimann]

I am looking for a casting material different than resin. So far I have used Smooth-Cast 300 which is a great product but the down side is that it is difficult to assemble a figure since it can't be bonded. I need the resin copies to give to the foundries as a reference. Maybe someone has a great tip how to bond two pieces of resin.

superglue works great, actually "C"glue from a model shop, or mix a small batch of 300 and used as glue, if you scotchbright it, then hit it with denatured alchol and even some viniger it will make bonding easier, bondo, jb weld, gorrila glue is really really good.

how can you use 300 as glue? it seems way too liquid. I heard that some people use shredded cotton to thicken it up and to fill in the gaps. Is that what you would use? Where can us buy that product?

I use EasyFlo-60 resin (from Polytek Development, which is the equivalent to smooth cast 300). When I cast my parts separate and then need to join them, I rough-up the area to be joined, wipe with alcohol and apply Epoxy Bond (Polytek) and let dry overnight. If there are gaps to be filled in, I use the Easy Flo-60 resin and thicken it using cab-o-sil or Poly Fiber II and make a paste to trough on. This plastic easily sands and can be worked with tools. Works for me.

Hi,
I've cast a lot of sculptures large and small in FortonMG95. It's a gypsum/resin composite. It's really wonderful. You can patch it months later, it takes paint beautifully, can be sanded, etc.
I also use a product by Aves, a two part putty, to patch after joining pieces of the Forton cast. It too is way beyond wonderful stuff. I've resculpted small parts on antique sculpture, fixed jewelry, etc.
But I really recommend you look into forton. If you visit my site www.jsesti.com you will see that most large sculptures, if not bronze, are cast in it.
Enjoy, J

**that's Apoxie Sculp isnt it?
I use Magic Sculp for the same purpose although I recently experimented with using it for "slip casting."
If you make the two part epoxy wet enough you can smudge it into a silicon mold(maybe a latex one too but I havent tried) and you can build up a hollow casting. Its a fair bit of work, but the results are great(oh and there's the toxic touch factor--its ok for smaller figures, but not so fun for large things).
The FortonMG95 sounds interesting though.

Take your resin and thicken it up with micro balloons. Make it thick enough so it won't run at a 90 degree angle. Add your catalyst and assemble your pieces. Easy as pie!
