Greetings All

I'm looking for a local supplier for silicone rubber for mold making

Example of stuff I'm looking for
http://www.hobbycast.net/siliconerubber.htm

Does anyone know if Home depot or Lowes sells something like it under a
different name? I would like to run down to the local store and pick some
up at a moments notice instead of waiting 3 days to get more in case I run
out.

PS: I've tried using Plaster of Paris but I need the flexability of
silicone rubber

TIA
Sal

Unfortunately, this isn't an item you'll find at the local home
improvement/hardward mega-mart. You need to find a speciality place. Not
knowing where you are, all I can say is that if you're in the U.S., TAP
Plastics is one place where you can find this stuff (what you're looking
for is "RTV"--room-temperature vulcanizing silicone rubber). Or a good
hobby store.

My local Hobby Lobby carries mold making and casting materials. If you have
one nearby, look them over. Mine carries Alumilite materials.

Ya know I really want to write something about the signature file in your
replies but I decided to hold back. Then I looked at your email addy and
that said it all.

Folks:

Ain't it just awful? Most folks' crimes got only
a few lines in the police blotter...
Discrim-i-nay-shun, I calls it.

Hmf.

Anyway, I have had some luck using cheap GE silicone caulking (the kind
that
smells like vinegar) to cast plaster models. Silicone I or the
competition is fine.
Make a wooden model, wash it with soap, and let it air-dry as a mold
release.
Molds don't last forever but they do work.

Cordially yours:

No Home Despot would have no use for it. remember silicone
compound has a decided shelf life and if you don't sell a lot you take
a loss when the shelf date expires. You will find a local supplier
only if you are near a large city where sufficient demand exists for a
specialty company selling it commercially to exist.
Personally I go to Burman's when I need small amounts like a
gallon but use Silicones Inc otherwise. I ignore the companies who
just repackage and sell to others at a large markup like Smooth On and
the other hobby companies. Silicones Inc or Burmans will sell you
amounts as small as a pint and still cost less then the hobby
repackagers.

I wish I COULD find it at Home Depot or Lowes :-(

I have heard in big cities like Minneapolis there are suppliers that can
get it for us, but there is usually a big minimum order and it is thus
expensive. This stuff has a shelf life, so do NOT buy in large
quantities unless you use the stuff very frequently.

Actually, it's not all that bad: I recently used some of my old RTV
silicone that had been sitting for a couple of years, and it worked
fine. The base, that is: I think the catalyst does go bad, and in any
case I used new catalyst (for some reason, my bottle had cracked open),
but the base was still nice and liquid, so I think it keeps pretty well.

There are a number of companies accessible online or via 800-numbers that
sell 1 and 2 lb RTV kits. Someone mentioned Silicones Inc., who I have
used. If the companies do not sell directly they will certainly refer you
to their distributor who will. The distributors will ship the stuff to your
house, FedEx/UPS, just like anything else. The "big minimum order" seems to
have gone the way of the snail mail order in most cases. MSC Industrial
Supply and McMaster Carr also sell various RTVs in smaller kits. They have
no minimum to my knowledge, accept credit cards, ship for less than most
hobby shops, and are quicker than NKR Models. I have bought from both many
times.

Ya - McMaster-Carr generally ships the next day and the prices are not

bad (for most items). I'm not aware of a minimum order - the only down
side for small orders is shipping.
