I think we are talking about two different, but similar materials. Mineral
spirits have a slower drying time than Naphtha. Both are petroleum
distillates. I know that we order them here as two different materials.
Technically, gasoline and kerosene are both naphtha's as well.
I think the original reference to "dry" naphtha is a more refined grade of
naphtha were pains have been taken to remove the water. I suspect
technical grade naphtha may not be pure enough. Technical grade
isopropanol also has a fair amount of water in it. If you are using a
silicone conformal coating, water is the last thing you want around.
Steve, we use Dow Corning 1-2577, which is a silicone conformal coating.
We don't use the one that you cite, but I would be happy to help if I can.
What questions do you have?

Steve,
On this website they equate it to Varsol, virgin mineral spirits. MY
GUESS would be that we are talking about mineral spirits where the
supplier has taken some pains to make sure there is very, very little
water in it.

Subject: [TN] "Dry" Naphtha
Howdy All!
I got a call and an email from somebody from one of our other
facilities asking about "Dry" Naphtha. I told her I had never heard
of it.
She said that on the spec sheet for a Dow DC6-1104 RTV, it calls out
to mix 80% of Dry Naphtha with it to use for conformal coating
I've done a search and can't find anything on Dry Naphtha, I called
Tomco-Harwell (where we usually get our chemicals), and called
Dow Corning as well, but nobody can tell me what Dry Naptha is, or
where to get it.
Could it also be known as reagent grade Naphtha?
Even better still, has anybody out there worked with Dow DC6-1104
that can help me out about how to apply it as a conformal coating?
Kind regards,
-Steve Gregory-
