Transparent conductive spray coating

Transparent conductive spray coating

Transparent conductive spray coating

(OP)
I have an object 3D printed with plastic PLA, I want to painting it (with several colors) and then add a transparent coating to make my object conductive. Does anyone here have any experience with transparent conductive spray coating ?

RE: Transparent conductive spray coating

(OP)
About the transparency, the coating should not spoil the paint.
About the conductivity, resistivity could between 106 and 109 ohms per square.

Try TechSpray 1756-8S

RE: Transparent conductive spray coating

Ohms per square what? Guess over three orders of magnitude, it doesn't matter much.

Transparent conductive coatings do exist (what is that- indium oxide they use on solar panels?), but not out of a spray bottle. But what you need sounds like it's only conductive enough to be static dissipative, not really conductive per se, and maybe that stuff Mcvyvr recommended will do that.

RE: Transparent conductive spray coating

the resistivity in ohms per square is independent of lateral dimension, since the effective thickness is what's important, and that's factored into the resistivity. That means that a 1 mm x 1 mm square has the same resistance as a 100 mm x 100 m square.

Thanks for clarifying IRStuff! It's a weird unit like mhOs I guess!
