    Does anyone know where I can get 100% silicone? Most selants seem to be quick dry (which is not 100% silicone) or else they don't specify.

    Sealants are a compound, not 100% of anything.

    Heh, no I want to use it as a cheap alternative to moulding rubber, for making duplicates of objects. Apparently the method works best with 100% silicone.
    This is what they can buy in America:

    No, I want builders silicone as a cheap alternative. It's a thing. Don't ask....

    EDIT: Obviously silicone is a thing, but what I mean is making moulds out of builder's silicone is a thing, popular on craft websites and so forth.

    As far as silicone goes you're probably best off starting with Dow Corning http://www.geocel.co.uk/catalogue/brands/dow-corning-7-series

    781 gets used on fish tanks etc as it has no anti-mould ingredients so maybe what you're after...

    Not sure how many of those are low modulus though 781 certainly is high modulus.
