What is the opinions using conductive contact dressings?

it's not a mess if you apply carefully and sparingly, posted on August 11, 2024 at 06:49:01

I use silver conductive grease by Chemtronics on plate caps and tube pins. This it most likely what the audiophile vendors sell under their own name. Mouser sells a 6.5G tube for $61.89; part number CW7100.

You are correct that it is important not to smear too much on the contacts. Chemtronics also sells the applicators which appear to be the same kind of wipe that women use to apply makeup: little foam pads on a plastic stick. The bottom line is that an almost invisible smear is what you want. I apply with cotton Q-Tip that I use over and over so as not to waste the expensive conductive grease.

It has been effective for me in reducing noise from plate caps and tube sockets.

Using the tiniest amount possible on rca's, barrier strips, bannanas and the like. I'll never use 20% of the Silclear.

According to the vendor, Mad scientist audio: "it is barely conductive" According to Chemtronics their silver conductive grease: Maximum electrical conductivity and thermal conductivity

"I am pretty sure any contact enhancer must (rpt must) be conductive. You know, otherwise it's a short."

If the contact enhancer is conductive then it's a "short". The enhancer is between the two pieces of metal that you want shorted together (a good connection). If the contact enhancer is not conductive then it's an insulator. If you have an insulator between your two metal conductors then you have an "open", not a "short".

Please tell us that you just mis-spoke and that you do understand the difference between a short and a open.

Lew Audiophile Posts: 11011 Location: Bethesda, Maryland Joined: December 11, 2000	I thought the superior conductivity of graphene depends upon its being in a monolayer (a layer with thickness of one molecule). Just smeared on to a conductive surface, does it behave as well in conductivity?

Lew Audiophile Posts: 11011 Location: Bethesda, Maryland Joined: December 11, 2000	I was just wondering, because getting graphene to coat a surface as a true monomolecular layer is the subject of many scientific papers. If not in monomolecular layer, there are data to say it is not as good a conductor as copper.

The fantastic review that Tre' referenced below is far superior to the 2-3 individual papers I found, but if you still insist, I will re-research the topic and post some references. But meantime, read the long review that Tre' referenced. I learned a lot from reading it myself. I am assuming from the get-go that you don't doubt the principle that graphene by definition is a monomolecular film (or a 2D structure as described in the review), composed of a lattice containing repeating units of six carbon atoms in a hexagonal arrangement. If you don't have that, you have graphite, not graphene. This is why I have always been dubious of audiophile contact enhancers that claim to work because of graphene content. I don't see how you can get a 2D film from a coated Q-tip or squeezing a tube. One of the papers I found described a method of coating silicon with graphene by heating to 1000 degrees; this was regarded as a possible breakthrough in solid state electronics.

I've made my own graphene contact paste and what I would call contact enhancer The paste is conductive. The enhancer is not. The difference is how concentrated the graphene is. The paste is highly conductive.

At a lower concentration the graphene is still visible as the enhancer liquid is black, but when put on contacts, it gets into the nooks and crannys of the metal, and adds only a slightly grey color to it. But there is not enough graphene for conductivity to take place across a flat surface more than a couple microns I would guess. But in something like an RCA plug where the metals connect, it increases conductivity. Yet doesn't short inside the plugs at all.

It works really well as an enhancer. It is my favorite sounding contact enhancer I have tried, and I've tried a lot over the years.

Very thin layers, not slobbered on with a Q tip or paint brush. Squeezing it out of a tube? Huh? Where do you guys come up with this stuff? I apply Graphene CE as an extremely thin layer, so thin you can barely see it.

Some you skeptics might consider adding to your arsenal of complaints - none of these Graphene CE contain two-dimensional Graphene, the Graphene is in solution as a powder.
