Hi Kontra,

I think you can give PVA glue a try. You'll need to thin it down with small amount of water like I suggested. I have built a few pairs of headphone using this formula and it proves to work well.
I'm also building a pair of ESL speaker using this formula to coat the diaphragms - so far so good.

Hi,

looks very much like the right stuff ;-)
I always bought these bottles:

Default Tesa glue - test

Wachara C.
I tried it. Unstable resistance. Depends on dampness. Does not suit anywhere.
Tried also phenol + nylon + black lead
Strongly smells, a gas mask, gloves, a heavy film. Not diaphanously, not beautifully.
Has decided to try this Tesa glue with ink and water

Many thanks Calvin.
Thank for the new recipe and for precise helps.
How your composition adheres{sticks} on mailar?
I test adhesion of a conductible finish so:
1. I cover{coat} a surface of an experimental model on which I train
2. I dry day
3. I measure resistance a high-voltage ohmmeter (a terminal voltage of the voltmeter of 6 thousand volt)
4. I stick down{I past} to a coverage office gluing fillet (adhesive tape)
5. Sharply I pull edge of a gluing fillet
a) The coverage remained on a gluing fillet
b) The gluing bed from a gluing fillet has remained on a conductible finish

Event b) the best outcome.
You so tested the coverage?

Kontra, You mean that:


1.You spread the conductive coating on a piece of Mylar.

2. You let it dry for one day

3. You measure the conductivity with 6Kv Voltmeter.

4. You press a piece of tape on dry coating.

5. You rip off the tape.

6. You see if the coating remains on Mylar or adheres to the tape.

Is this correct? If so, it's not a good method of testing the life span of a coating. The coating can loose its conductivity without leaving its base, the membrane.

Hi,

I have old panels standing in a rather wet and open cellar. Every now and then I test them on function. For ~5 years now there´s no change in performance. Additionally there are some guys using this formula and none has reported any problems.
So I´m quite confident with the longtime performance of the coating.

Hi Calvin,

Thank you very much for your confirmation that your recipe really works. My recipe has been performing well for the last few weeks also. Time will tell.

Default adgesia

Calvin and JonasKarud
About yes! I always remember as to do{make} measurings.
Thank for your care
(I Ask to take into account linguistic difficulties, my computer the translator cannot pitch{impart;transfer} you mood of my mind{wit}, beforehand I ask to excuse me for involuntary sharpnesses
At me negative experience when the coverage has not adhered was, the adhesive tape separated, I have made practical experience, have collected, in three months had "three" membranes. (humour)
I began to think this occupation and have come to an output, that all that acoustical pressure which we hear forms by a film mailar which drags behind itself such coverage. And thus adhesion should be. And adhesion "resolute" a problem costs{stands} so: how to create a gear (a means of measuring) (a calibrated counter of adhesion) at me such gear is. If was exact. With one division. You with Calvin have shown me a sight at it on the other hand.
I am very grateful both Calvin and JonasKarud.
I have recollected now as at MJ Dijkstra have caused light misunderstanding, my problem on adhesive force of his{its} coverage. (Humour)
Necessarily I try recipe Calvin in the experiences.
As glue in the recipe - very sticky.
Once again thank both of you
English at us my computer probably as at the pirate with a sabre.

I finally got some work done on my electrostatic setup this weekend...

Not much on the headphones, just found a donor frame and made some transitional
pieces for attaching the bale to the stator frame(the grey pieces of plastic).

I did most of the prep work for the chassis for my energizer as well; 1/8" aluminum plate
with ipe side pieces salvaged from a high end deck years ago.

Still waiting on parts!

@Wachara, if you would like me to post this in an independent thread let me know. I thought it might be nice to have a single resource in this thread for anyone wanting to build a set.
