That is correct. Naphtha is a solvent that is derived from petroleum.
Heavy (wet) naphtha solvents are used for making turpentine, mineral
spirits and other solvents. Dry naphtha has very little moisture (less
than .05%) and is used where a cutting agent is required when mixing
epoxies (such as conformal coatings), paints, etc. It evaporates very
quickly.
Be careful when handling it, it is made from gasoline byproducts. It
usually contains toluene and benzene and other toxic materials and needs
special precautions for ventilation and breathing apparatus.

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-
