Does anyone here use this or a similar product to seal their stators or other electrical components?


Just curious to know if it's worth the extra expense and what your experience has been. This stuff is hard to find and runs $15/can on Amazon. Are there other coatings that would work, or do you even bother?

I use Dolph's EB-41 on ceiling fan stators and speed coils if they buzz. It tends to help quiet them down some.

Are you able to get the EB-41 locally, Derek, or do you have to order it? I can’t seem to find anyone who carries the Sprayon EL2000 near me, so that’s why I’m trying to figure out if it’s worth the hassle. The issue actually came up regarding the power transformer on a ‘36 Philco radio I’m working on restoring. The Sprayon EL2000 was suggested in a video as a good coating for preventing corrosion. I figured maybe there was something members here use on fan motors and coils that would be a good alternative I could source locally, or at least less than $15 a can. I wouldn’t mind spending the money if it has broader applications such as fan stators and coils. I just worry about heat and how it might react with different tapes or wraps on windings. Not sure the black EB-41 would be desireable on the radio transformer, but, then again, it’s under a clamshell...

Aaron, I purchased it from eBay, but I understand that it's only available sporadically from that source.

Thanks for all the replies. Looks like McMaster Carr is the better deal.

I've used Sprayon EL-600 insulating varnish for many years.  I get it from WW Grainger.  It is a very good electrical insulator and dries as quickly as lacquer.  Use it on rewound stators and speed control choke coils.  The magnet wire used in the stator windings has an insulating coating that I am afraid may be affected by lacquer.  I use Dolphs on  the original stators.

Dolph's is the cat's meow. It rocks. Plus it comes in black. Win.

I'm pretty sure I want clear on the radio chassis components, but Dolph's sounds like an excellent choice for fans. I may just shell out the $ for both.
