Re: Silicone

I need to fill a mold with silicone to obtain an object made in this material, but it is too dense, so I need to make it much more fluid..
Which kind of solvent can I use?

Thx Lollo
 

Re: Silicone

There are so many variations of silicone sealant that trying to find a solvent compatible with the one you are trying to use would be impossible without manufacturer's data. If your sealant smells like acetic acid, the acid is probably part of the catalyst - not the solvent.

There are two part casting silicone rubbers that aren't too expensive. You would be better off getting one of those and not trying to thin construction sealant. Most of the silicones suitable for casting are actually listed as mold rubbers. Take a look at the following for examples:
