Something instead of Resin Pu ? Allergic problem.

Hi every one.

I am really worried because it is sure that I am allergic to resin PU. I have problem each time I work with it on her liquid form, less when it is hard. But I can't continue making doll in Resin PU if each time I use it I am sick.
So wanted to ask here if you know something that can be use instead of Resin PU, and can be work with silicon mold.
Does someone here test bioresin ?
I have a look on the web but don't see what I can use that will be less toxic than Resin PU but with the same property.
I can't stop making doll as it is my work, but using Resin is really a problem.
Thanks by advance for your answer.

 

:s well it is true that it isn't sure that it will fix my allergy problem I'm really sad, there is a french distributor www.bioresin.fr I'll call them this morning to discuss with them of their product. Hope that they could purpose my something interesting. I will let you know.

 

Hi morgan thanks for your answer.
Yes there is porcelain but I would have to change totally the way I work.. It suppose plaster mold and things like that.
I call Bioresin yesterday, the man I had on the phone told me that their resin is more liquid that pu resin I used. It seems to be a really good product but... it is TOO expensive.
Price is 42euros per KG and they sale kit of 10 kg..; So unfortunately it is 4 times more expensive that regular resin and way too expensive to make doll.
I made search and finally try yesterday something I have at home and never get the time to try. I don't know exactly what is the name of this. It is a sort of Ceramic powder that can be used in silicon mold, you can color it. So I made a try on an headback and it is stronger than resin, hard like a stone. Really impressive ! It looks a little bit like porcelain. And it is user friendly so great for me.
I think I will try on a complete doll and see.
Morgan I allready in contact with a manufacturer for my doll, and have one that will be for sale very soon, but I want to continue making art doll, fully made by hand and a manufacturer can't do that for me. There are two different things.

 

Yes it is really sad that bioresin is so expensive
Well The ceramic powder I found, look like plaster, but really thiner. You mix it with water, and you can add liquid color or powder color in it so the color will be in the whole piece.
I don't find what it is exactly. The french name is artestone. I copy you the english text that I have.

Artestone is a hight quality ceramic casting powder, which is manufactured on the basis of phosphates.
Form parts made of artestone are distinguished by their extremely hard and solid and yet abrasion resistant surface.
Hydrophate is also mixed into the artestone which means that the cast parts do not absorb any liquids when they are dry.
You can cast it in silicon mold.
adding color in the casting mixture with universal color concentrate.
You can made it looks like china by casting past primer and glaze them with a transparent cold glaze.


I think it looks really interesting, because I don't want to work with porcelain. And need something really strong.
But this means really doll art, as I isn't possible to remove the paint and it means finding another way to work on doll.
But it could be great.

 

technic information :
mixing ration : 4:1 water
casting time hardening start 8/10 minutes
expansion controlled 0.2%
surface hardness dry : 315N/mm2
compressive strength dry : 75N/mm2
flectionnal strength dry : over14N/mm2

temperature resistance dry : up to 130 °c


there is also another product call kersolith that is use to make hollow form with the same technic as porcelain.

safety :

artestone is free of any dangerous components. Children over the age of 5 years can work with artestone under the supervision of adults. Do not inhale or swallow the powder.

 

twigling> what do you think about it ? Does it sound great to you ? As I Know you are a pro about casting material and other things like that I am interested in your opinion about technical information I put here.

Kwmelvin> oh yes I know this material. It is also call cold porcelain, they sell that on miniworld website. But it is necessary to use plaster mold for this, and it look so difficult to make :s
it was seeley so they don't make sleap anymore.

The only thing I see now that can be annoying with artestone is his weight it is really really heavy compare to resin, so it could be a problem with big doll, and could modify the balance of the doll.

I will make a junk cast of Sandre to see how it look on an whole doll.

 

yes it is necessary to make a test.
Well I try and it is a little complicated to color artestone.
I have also thought of "plâtre synthétique" Synthétic plaster that looks like porcelain, but stronger I can be poor into silicon mold. Need to try this too.
Twigling I have try artestone on a hand of Sandre, the hand is beautiful, I let it fall on the ground and it didn't broke but if I try to broke the finger they broke. In another way if you try to do that with a porcelain doll the finger will broke too so I don't know..
