[filmscanners] Re: PEC-12 (was Modern photography)



I don't see Methanol listed in the PEC-12 MSDS.  It is listed for the
E-wipes.

Carbon Tet, is non-flammable (and is banned in the US) so I doubt that
it is used in this, since it is flammable and sold in the US.

Kodak film cleaner contained (this is old - I don't use it often)
heptane and 1, 1, 2, trichloro-1, 2, 2, trifluoro-ethane, and is
considered flammable.

Just for the heck of it I did a Google search on "Fruity odor" +Solvent
and come up with quite a few hits, since a lot of organic solvents are
fruity in odor especially ethyl and methyl ethers, but this one caught
my eye:


http://www.lpslabs.com/Products/MSDS/203020.pdf

This product is a degreasing solvent and the msds has a lot of similar
descriptors to the PEC-12.

My guess is that PEC-12 is a industrial product made for other purposes
and sold in small bottles for a lot more money than the bulk version
sells for, and that is why it is a "trade secret".

Personally, I try to stay away from products that are so well hidden in
their contents to make them potentially dangerous if one ends up in an
emergency, because the MSDS is incomplete.

If a company like the one shown above is willing to spell out pretty
closely what their product is made of, the only reason I can think of
for PEC-12 to be so well guarded is because it is just a repackaged
version of something that sell much less expensively for another use.

That's my opinion.
