conformal coating

[Archimedes' Lever]

Context is everything. Isn't Torrseal a polymer?

No. It is a brand name for a product.

If you thin it, capiliary action will
draw it into wire strands and crevices.

So will a nice vacuum chamber.

Do you googlers even KNOW ABOUT the search side of google?

Searching "conformal coating" with quotes returns "about 163,000" hits.

Now, go and do your own homework first.

Good Luck!

I think you have answered your own question.

With 163,000 google hits to wade through and knowing how reliable
Google information often is why are you averse to someone enquiring of
a knowledgable / experienced person.?

Failing to learn and adapt from the knowledge and experience of others
is how the cowboys operate.

keep your spurs clean

So, did you bother to do the search, or did you just say "screw it!" and
come back merely to whine and snivel about the difficulty of the
assignment?

Everybody has a favorite conformal coating - I have a couple, depending
on the application. What are your parameters? How about a spec of some
kind? Are you willing to participate in your own research?

Thanks,
Rich

It is NOT "google information" you retarded, know nothing piece of shit.

The hits are real web pages that have NOTHING to do with google. Google
is merely the search engine.

Your IQ was already below 50, but this post you made here just dropped
it by a minimum of ten more points.

Your failure to understand just what a google search is, is indicative
that your logic is severely flawed, not to mention the fact that you have
also obviously been biased by the peer group you 'hang with'.

In other words, you're a gossip retard.

I need a conformal coating that will protect a pcb in a saline
atmosphere, maybe even the odd small drop of saline will land on the
pcb.
The temperature is room temp and the pcb dissipates only the odd mW
(no hot components)

Potting is not an option but dipping is!!  (odd I know but
nevertheless)

Has ayone knowledge/experience of a suitable conformal coating?

Thanks

I used flowable silicon from RS apply on the pcb, it work !. But still
finding a way or liquid to dilute the silicon .

Probably one of those silver platter asswipes that gets a job where he
gets to stand around doing next to nothing all day, and calls himself
participatory.

Real knowledge escapes these dolts, even AFTER they have "experienced"
solutions.

The only solution I want to experience right now is a nice Bass Ale...
or two. Currently one of the few good things to emerge from across the
pond.

He hasn't acknowledged, let alone thanked, those who have participated in it
for him, so don't hold out much hope. Anyway, I think he's not acting like
the kind of professional who REALLY throws out 100,000 plus of anything. And
even if he is, if he throws his head up and sneers at my suggestion of yacht
varnish, he's a fool. Even if that's not the end of his search, it's a damn
good start, considering it's made to satisfy EXACTLY the demands he's
expressed so far.

Many conformal coating are "varnish" based, as are transformer
impregnation media.

He is lost if he scoffed at your suggestion. But we all did see that
coming.

 

[Archimedes' Lever]

I realised that the choice of materials
really is not that sophisticated..

Actually, it is. It has a very high temperature capacity, which many
polymer based coatings do not necessarily have.

, if it was crap the industry would
have rejected it by now.

Precisely. That was my original point to all those that claimed that
sea water would breach it.

If HV supply makers use it, you can count on it sealing just about
anything up. Damn near to hermetic proportions.
