I use mostly laquer thinner for brush and airbrush cleaning and gallon cans
of thinner form the local hardware store for thinning. I still have a few
name brand mini cans of thinner Testors, Aeromaster, (new) Floquil but I
think when they are gone I'm gonna stay with the generic thinner which has
worked fine in tests so far.
I also bought a pint of MEK 'cause I just happened to see it. What can I use
that for?

Not a simple question - floquil paints were originally laquers - back in the
60s and 70s. The main solvent was Xylene. They then toned it down to
toluene. The old original paints would graze plastic even if airbrushed -
unless you went with dusting coats - which were great the paint basically
bonded to a melteds surface.
With OSHA and other contsraints they went to enamel base and dropped many of
their colors. Some of us still believe they were the beat paints ever
created.
Dio-sol changed with the times.
Getting back to your question. Depending on the vintage its a great or
really good solvent for cleaning things like airbrushes - but nasty stuff to
inhale or get absorbed into your skin.
Do we know about when they changed the formula 'cause now I'm thinking it
might have been before I acquired my paints and Diosol. I still see Floquil
thinner advertised as Diosol which clearly isn't the old stuff. Can a
difference be told from the odor?
Frank
As to the MEK (Methyl Ethyl Keytone) is used to be used for bonding
plastic
(Glue). I works really well as it would simply melt each surface and
when they
were joined and dried they were literally "welded" together.
MEK, however, is extremely dangerous as the fumes are directly
absorbed by
the lungs and also can be absorbed by the skin, It is a known
carsinogen(Sp)?
Most modelers ceased using the stuff years ago and I thought
(obviously mistakenly) that it was no longer marketed.
Yikes! Hmm, now how to dispose of it?
Frank
Methyl Ethel Ketone is also an ingredient in some commercial paint
strippers, including "aircraft strippers".
http://en.wikipedia.org/wiki/Methyl_ethyl_ketone
It can leave a nasty chemical burn if it touches exposed skin.
Contact your local recycling center to see if they'll take it, or for
other disposal methods.
Hey Frank,
don't dispose of anything just yet. Lots of hobby chemicals are nasty
but very useful when used properly.
OK, first Dio-Sol. You made me go digging through my stash just to
help out a fellow modeler! :-)
I have the "original" formula DIO-SOL in a 16 FL. OZ. can. It was
purchased sometime in the mid 80s and it was for the original Floquil
paints of that time (which still attacked polystyrene when applied
without Floquil Barrier). Remember Barrier? :-)
Part number on the can is 150001 (not really relevant as the part #
stayed the same even when they changed formulas). But the label has
other important clues.
1. contains xylol, toluene and aromatic hydrocarbon solvents.
Photochemically reactive.
2. address on that bottle is Amsterdam NY.
This version of SIO-SOL was made for all the original Floquil Railroad
Colors paints. Ones in square and round 1 oz. bottles with red
printing on the labels. Various versions of those labels described
their contents as xylol and toluene, sometimes alongside of petroleum
distillates. All made in Amsterdam, NY.
Next, I have a 8 FL. OZ. can of a "new", "REV 1, plastic compatible"
DIO-SOL. That one was purchased on Jan. 2002 (yes, I became anal
enough to write down purchase date on my paints). Its part number is
140001 (because it is a smaller can than 150001). Label only shows
that it contains petroleum distillates. This version of DIO-SOL was
made for the next generation of Floquil Railroad Colors. First batch
of those new paints came in round 1 oz. bottles again with red
printing on the labels. But the paint bottle labels also stated (in
red print) "REV. 1 FORMULA Compatible with plastics. No barrier
needed. REV. 1 Colors are compatible with Dio-Sol and regular formula
Floquil Colors." It also states that paint contains "petroleum
distillate". Mind you that the "REV. 1" Dio-Sol can I have just
described has no "REV. 1" indicated anywhere on its label but it lacks
the xylol and to toluene from the warnings.
Another important clue as to this can of Dio-Sol being "REV. 1" is
that it was made in Canada in Weston, Ontario.
Going back to formula revisions, the current Floquil paints have
labels with black logo and red printing and they no longer mention any
"REV". But I assume that they are identical) or at least very similar
to "REV. 1" paints.
I don't know why Floquil made things so confusing for modelers. It
seems that the original and REV. 1 paints and Dio-Sol are all
compatible. I think that the original Dio-Sol would thin REV.1 paints
fine but it will cause plastic crazing if directly applied to
polystyrene.
Next, in the name of science and being helpful I did the sniff test.
Original Dio-Sol has a "sweeter" smell than REV. 1 Dio-Sol. I suspect
that is because of xylol or toluene.
I hope that this info helps you out.
I also want to mention MEK. I don't recall it ever being used in
Floquil paints. It is a nasty chemical but Testors Plastic Liquid
Cement still uses it. I have a 1 oz. bottle of that cement (part #
3502) and MEK is still listed on the label. It has a "copyright 2001"
and I purchased it on 2003. So, MEK is still utilized in plastic
modeling. If common sense is being followed than MEK should not pose
any more hazard than other solvents we use in building model kits.

> Yikes! Hmm, now how to dispose of it?
Why bother? Just consider it lacquer thinner. Xylene, Tolulene, MEK,
Acetone, Trichloroethane, Methanol, and Methylene Chloride (as paint
stripper) are all readily available in hardware stores. Lacquer thinner is
just a mixture. There is nothing really to set it apart from any of these
other solvents, safety-wise. Just take the appropriate measures.
Floquil changed because of OSHA? Pfft! Another urban legend. The real
reason has already been noted: You couldn't use it on plastic models without
a barrier coat. When plastic became the material of choice in the 70's for
railroad models it just didn't make sense sell a hobby paint that couldn't
be sprayed on hobby kits without an airbrush and a real rigmarole, and
couldn't be brushed at all. Look at Peteski's post about the new labeling:
"Safe for plastics!!" They had to change to stay competitive. (Which I
guess they weren't anyway, leading to them being bought by Testors or
Testors' parent company.)
There was another similar BS story this month: Tenax-7R was no longer
available - it has been banned by Obama and the EPA!!! After a couple of
weeks of the usual
"goddamm-socialist-Obama-entire-country-is-going-to-shit-they'll-be-banning-war-models-next"
posts, someone posts that after talking to the manufacturer (a small
company), no it *wasn't* banned, the owner just had some personal problem
that prevented him from shipping any for a couple of months. Hardly an
interesting a story, and not surprising that most people instead ran with
the one that supported their own fears and prejudices rather than checking
to see if it was actually true. More fun that way, I suppose.

Yeap that racism so bad it prevented his taking office.
Or am I racist for disliking his politics?
I'll take whatever name anyone wants to call me for thinking Obama's a
dangerously naive, woefully inexperienced, insufferably arrogant and
reckless ideologue who is in the process of frittering away the strongest
political hand enjoyed by any incoming US President in recent memory. Obama
is amassing a cache of political miscues that is due less to a strong
opposition and due more to his delight in governing with an abrasive and
divisive manner that is both incapable and undesirable of forming bipartisan
consensus. When he's not out snuffing the life out of his very own key
political initiatives through gross political ineptitude and hubris, he can
be found foolishly wading into matters of such little consequence one would
reasonably assume that given the enormity of the responsibilities of the
office of President, they would be far below his pay grade - so to speak.
And I should vote for this guy in 2012, why?

Hell if we had to vote for a rock star why couldn't it have been Ted
Nugent? ;)
is he american? ok, i'm a britsnob musically. he was in some bad?
if it ain't from machester or the smoke, it's too normal.
you do realize i was yanking you severely? or was that more?

I had kids on my dorm floor that actually went to school with Terrible
Ted at a couple of the area high schools he got kicked out of...
...which means I got to hear the back-story behind the line - "Mother
Cruz is a bitch now, baby"...
I'd vote for the guy...

Don't know and don't care. However, regardless of your persuasion as an
American you should perhaps give the President more than 200-odd days in
office to work before making a statement like this, one that sounds innocent
but is backhandedly stating that you won't vote for him three and a half
years from now no matter what he does. In practice, allowing only two
hundred days *is* effectively saying that, no, I won't even give him a
chance. If McCain had won, and was struggling, what would you think of
Howard Dean saying at this point: "The President's is obviously a failure,
given that nothing has been accomplished"? (Don't bother posting how if
McCain this, if Obama that, things would be different. That's not the
point. The point is that when somebody never liked the guy in the first
place a charade of fairness like the statement above doesn't work.)
Besides which, look back to my original story. People don't care about
facts. They choose to believe whatever meshes with their pre-conceived
notions. If somebody thinks Obama is bad, they gobble up - without any
evidence or confirmation - that he is responsible for destroying their
pastime. In fact they expect no less.
Remember Dan Quayle? "If I knew I was going to someday visit Latin America
I would've paid attention in Latin class"? Well it turns out he never said
that. It was a joke, but everyone was certain he was dumb enough to say
something like that, so it became fact.
http://www.snopes.com/quotes/quayle.asp
Even the Washington Post printed an editorial about it, chiding those who
passed it on as fact and concluding (as I recall) that enough was enough and
that as VP even he deserved to be treated fairly.

Nuff said.
