Hi Guys.
Rodent just brought up something that I have been looking for. Does anyone
know of a insulating and non conductive coating that can be applied to
electronics. Years ago we used a thick liquid that when dried formed a
1/16" coating on whatever it was applied to. Two coatings would give 1/8"
coverage. We used it on most of the tools in the power plant so if someone
slipped with a screwdriver or wrench it woudn't short. The product was call
INSULEX but I don't think it is made anymore. I have searched the net
looking for it with no luck. Has anyone had experience with something
similar? If so any recommendations ?
Thanks
Eric.

My experience with most tool-type coatings is that they don't adhere
tightly enough to assure moisture won't creep between the coating and the
part coated. Not much of a problem with tools, but a big one in your
application.
Want a zillion good references to moisture proof coatings for electircal
circuitry and printed circuit boards? Go to http://www.google.com and
search on the terms "conformal coating."

plastic-rubber coat on pliers. I have dipped small PCBoards in it to
waterproof them.

Is the stuff you are talking about rubber-like? If so, two products I use
are "DipIt" and "Tool Dip". This stuff is thick and heavy, good insulating
qualities, but would cause heat build up on electronics. I use it to coat
flybacks and other equipment I plan to punish with high voltage.

Rodent mentioned conformal coating. I thought he was just talking in
general about something that conforms to the shape of an object but had no
idea that was really what that type stuff is actually called.
I didn't get a chance to get up off my chair before I got 4 replies. Thanks
guys!!! I looked ay Google under "Conformal Coatings and got tons of
sources. Again thanks

SPRAY CAN, I think colors were Red and Black, Seems like it was around
$9.00 a can. Been 3- 4 months since I saw this.

I've potted boards in epoxy, but then they're virtually
non-serviceable. A guy I know makes custom products
for musicians ... super stomp pedals, etc. Fills the
whole box up with black epoxy so nobody can copy his
designs (old trick)... it also conceals how simple the
things are, considering the outrageous prices he charges.

I think they also call it liquid electrical tape. This is not the same as
the conformal coating I am familiar with and I'm not sure how this would
work on a circuit board.
What we use at work is silicone based and dries semi-clear. You can get it
as a spray-on or brush-on product, and it comes in several thicknesses as
well. It also has a UV dye in it so you can use a black light to check your
coverage. I think Mouser and Digi-Key sell the spray-on version.
You need to be absolutely sure you are finished working on a board before
you coat it -- this stuff is nasty to deal with when you have to rework a
circuit board.

When I worked on oilfield tools there were several modules we potted to keep
competitors from reverse engineering. Before we potted the boards we sanded
off all the part numbers on the transistors and IC's.

It is easy to use, just spray on
and it dries to touch in 30 min. and cures fully in 24 hours. It works well
since most of our equipment is at sea
for 2 year deployments and a few have got full of water but the coated boards
survived most of the time. Newark,
Allied and some others carry the Techspray line so it should not be hard to
find.
