I'm looking for some sort of dielectric coating that can be used at high temperatures. I'm working on trying to create a voltage point charge in a high temperature steam environment using a coated accupuncture needle. The goal is to be able to coat the needle thinly and uniformly, leaving only the very tip of the needle exposed and electrically conductive with the rest completely insulated. Therefore I'm looking for something that can be applied in extremely thin coatings (~.05mm thickness) through a dipping process, meaning it has to have a low enough viscosity (~200 cP) to achieve this thickness. The coating should be resistant to cracking once cured and be able to adhere to stainless steel accupuncture needles. The steam environment that the coating and needle will be subjected to will have temperatures ranging up to 500 deg C.
Do you have any suggestions?
So far I have discovered a few coatings made by Aremco (SGC4000 and GC4000) that seem like they may work. Has anyone had any experience with these coatings?
Thanks!
