Subject: Silicones Again
Date: 1992-07-07 18:24:02 GMT

I don't want to beat this subject to death but I think I need to make a couple
of points about my last post on automotive grade silicone sealers. We have been
talking about silicone as if it were some standard product but in the automotive
field the number different kinds of silicone sealers is large, each with
different properties. Some resist gas and oil, some can fill large gaps, some
can fill very small flat surfaces, and some can take very high temperatures. The
point I am trying to make here is that these sealers have different formulas,
things are added to the sealer to get the different features. These sealers are
tested on cars not on people, so because it will not breakdown exposed to gas
does not mean that it is safe for contact with food. As I said before I am sure
there must be some tested and approved food grade silicone sealer out there
which would be far better to use for brewing.

Looking forward the the OBF and over 40 different microbrews, July 17,18, & 19
