Conductive Paint

I know Stewmac sells conductive paint, but I found a company locally (Cape Town) that sells conductive paint. Now, this is epoxy paint, so you'll need to pre...

Great, thanks for that - I'll check it out.

Tonedef, I'm trying to find info on that on the web, there doesnt seem to be much?

Tonedef

Try searching for upol weld #2 copper. Thats used for mig/tig welding but is the same sort of thing.

not cheap, 300 van riebeecks a can, excl vat.

Ok, thats an decent option. The paint from Stewmac is slightly cheaper - without shipping - so its viable.

There's an acrylic version which is slightly cheaper and which will probably suit the application better. Look at the blue "customers also looked at xxxxx" links on the right.

Great - thanks for the assistance!

Tonedef

No probs! Hope you get something that works for you! I'd hate to have led you down a minus R300 path.... ?

Sidecar

Yeah, well the trick is to find something that will adhere to wood - or finding the correct primer for these to work!

Tonedef

Spraying it directly onto the wood should work fine, otherwise you can always give it a thin coat of wood pre-sealant beforehand.

Sidecar

Ok, I suppose I can always test it on scrap beforehand...

Tonedef

We want a FULL test report including pics! ?

Check out reply no #17 here . . .! (Question about conductive paint for shielding)

It really works! I use it now all the time! You can even layer it if you want, to give even thicker shielding!!

Cool Slyd, I'll check it out to see if I can find some of that tape.

Tondef, the only aerosols I could find that contains metal are zinc based (Zinc should be fine) but it’s to cover rust, and the can itself doesn't tell you what base the paint is made from. So I'm not sure if it would adhere to the wood, or how to prepare the wood. I can't find any suitable welding copper paint (unless this is the same stuff)

BTW…The Christensen stuff I mentioned earlier only gets sold in large quantities and is extremely expensive. So that’s a no-go.

Tonedef

I'd give the inner wooden surfaces a thin coat of polyurethane varnish - that will give you all the surface prep you need to get proper adhesion for the metal spray.

Another thing, just because a paint contains metal, doesn't mean it's conductive....
