You may also want to check out factor2.com. They may have what you need.

Btw... Does anyone know what the shore A value of the silicone that abyss currently used in their doll? I'm going to need to do some repair and want to know what the starting value is, and I'm going to go a little bit harder, so that hopefully my repair will be more durable than the original silicone.

In Australia. Dalchem.
http://www.dalchem.com.au/
Go to the website for info. I can tell you their Soft Translucent Silicone (2 part tin cured) is compatible and works well. The smallest amount one can buy is 550 gms. There is probably a connection to an American outlet.

'Smooth on' in Australia.
http://www.rowetrading.com.au/
Here, at any rate, they only do platinum cured silicone. The eco flex 0030 is the one with the same softness. However it is not compatible with RD tin cured silicone.

My advice is to get the catalyst and silicone together as otherwise you may have compatibility problems.
The websites above have information regarding softness and 'shore A' or otherwise one can google such info. And use links provided.

Mahtek did some tests with the catalyst. pm him if you still have difficulty.

Muzza,

What do you mean? Can you not use platinum silicone over top of already cured tin silicone? Or do you just mean the catalyst for platinum silicone is not comparable with tin silicone if you are mixing up a batch?

Both.

If you mix 2 part platinum cure silicone and apply to already cured tin cure silicone it will not set, but remain gooey. And vice versa. Apparently there is some chemical element in the different silicones which prevents each from curing.

Obviously the catalyst for one is thus different to the other and will not be effective in curing. Though I will stand to be corrected on this last point if incorrect. I am not doing a trial to find out.

Which is why I recommend you buy both parts of the 2 part (ie silicone and catalyst) together as otherwise you may have problems with curing.
You have a RD therefore you must use a tin cure 2 part silicone.

PS: I am not a expert. There are others on the forum who are. Perhaps they can advise better.

I've ordered from smooth on. I'm using it on my B5 doll now. The catalyst I got is a pink tint, so keep that in mind when you are ready to mix with the silicone. It may affect the skin color. The only clear catalyst I saw on the site was for the platinum silicone. I was impressed with the speedy and discreet nature of the delivery from them. Plus the price was right (I paid less than $80 for about 2 pounds of silicone... about $20 of that price was shipping)

Thanx folks...

(Luv this forum) I have ordered the 2part from fxsupply. I will try the others if it doesnt work out. I have enough of the original catalyst,
silicone, to mix a small batch together to test its compatability..(I didnt know about the diff of tin vs plat.) but wanted to test first anyways. So what youre saying is the Realdoll incorporates tin based silicone, not platinum? whew! glad I ran the post....

thanx Shmeagle

(ps which is stronger tin or platinum based?)

Ahh, and they say an old dog can't learn a new trick!

Hello Everyone,
I am new to this forum, after learning some of the silicone I provide as a distributor is used on some real dolls.

We offer tech support on silicones, although the applications here are a little out of the usual for us, the technology is the same.

Regarding Tin and Platinum based silicone--yes, they are different systems. Platinum will become "inhibited" against any tin rubber, or tin contaminated molds/tools. It will not set up.

We are developing clear silicones, mostly platinum, but also tin, for use in prosthetics. These will be tintable in flesh, and come in varied firmness and softness.

I am somewhat prepared to be bombarded with questions, and just ask for some patience with my replies, and I will do what I can to assist and direct everyone.

I currently have an excellent adhesive for silicone which we just had approved by a major account. I am in the process of getting this packaged in tubes, and hope to offer it soon. It can be used to halt larger tears when the siliocne gets cut.
