conformal compound/coating where to get

[littleowl]

I am wondering from a money standpoint what is Dow Corning conformal compound and can I go to my local autoparts store or something and get something that is the same!?!?! Also in my looking I found on the Dow Corning web page you can get free samples!! I would get some but I don't know what to get!! the site addy is http://www.dowcorning.com

In the uk I get mine from maplin electronics.

I think the closest thing in the US is radioshack.

There seem to be loads of options on the dowcorning site, im not sure exactly which ones will be best.

But for TEC application I think this will work

Although there might be better ones.

As for your question about what coating is made of...

Im not sure exactly whats in it.

But its not like di-electric grease.
Its much more like varnish.

Three kinds I use: the Dow Corning in the syringe that Danger Den sells. It's good for beading edges of sockets and neoprene sheets. It's thick and dries hard.

The Aerosol spray is good for covering large areas such as the back of MB's and Graphic cards. Don't get it in sockets or connectors.

And a brush on type in a small bottle for detailing areas around sensitive components and connectors.

Most commercial electronic supply houses carry all three kinds; you’ll have to look around.

I got a free sample quantity last year from DC. It's in a liquid form for syraying applications. I decided to use this product which worked just fine. http://www.jab-tech.com/MG-CHEMICALS-ACRYLIC-LACQUER-CONFORMAL-COATING-pr-2713.html

thanks premmer I guess what I am wanting to know most of all is can I go get something at say walmart or auto parts store that works the same and cost less then dd sells theres for!! I use what dd sold to me but I keep taking my tec off and putting it back on so I run out and have to get some more and when you add shipping it starts to cost a good bit!!

No, don't use anything that is not labeled conformal coating for electronic circuit boards. Something else may work but you won't know for sure if it reacts to other materials, retains moisture while drying, has capacitive prosperities or will it come off.

[littleowl]

that is why I posted the question!! I think we should be able to get it balk or a little more at a time cheaper!! I want to know has anyone been able to get some and where? or what is conparable in the stores around here!

You "can" use white thermal paste in the place of dielectric grease.
Messy as hell to remove but it works.
