It has similar sort of thickness as ProGold contact cleaner/enhancer, so like a thickish oil. The idea is to use a very small amount on a contact, (if there's too much you can absorb with tissue.)
It seems that in order to act as a superconductor, graphene must be in its 2-dimensional form, a one atom thick layer. I am trying to visualize how that works in the context of a paste you can apply to the surface of an electrical contact junction.
Graphene *is* an allotrope of carbon that is one atom thick. That's simply what defines it. You don't get other forms of graphene. You do get different sizes of graphene particles,etc, but they are all one atom thick.
Also it's not a superconductor, it's just a very good conductor, better than silver and copper.
I should not have used the term "superconductor", which has a specific meaning. I meant "super" as a conductor.
The chemistry is very complex, as I mentioned and you probably know better than I, but it seems to me that the conductivity of "graphene" is not always the same in all of its potential commercial forms (graphene flakes, graphene oxide, CVD graphene, for examples). That's what I was referring to. In certain complexes that might impeded the degrees of freedom of the pi electrons, doesn't the conductivity suffer, at least a little bit?
So if one uses the "right" amount of MSA, there is no migration?
...if that's what you mean. %^D
Sorry. I should have resisted. I'll go quietly now.
I find that it has a tendency to migrate to my fingers - but it washes off. But otherwise, how can I explain? It doesn't seek out tiny crevices like say WD40 does, but put a drop on a stranded wire, it will find it's way into the strands after a while. One idea of the oil-like base is to allow the graphene to move about in a limited manner to find the places it can work. So it depends on whay you mean by migration.
Yes we do plan to stay in New Zealand. We've just moved from 'south of Auckland' to New Plymouth and plan to stay put. We are a couple of inches off the right side of the picture.
Lastly, I've just made the 2ml sample size tubes available on our website. The larger sizes will come soon when the larger bottles arrive.
Just a quick note to say that the 5ml and 10ml bottles have arrived now (and I'm busy filling them up).
....is a bit more viscous than other oils, and hence will not migrate as rapidly. That's what I was wanting to know. With careful application, and placing it "just so", the MSA graphene should largely stay put.
My long experience is with Stabilant 22....one only needs a small amount to spread (with the tiny applicator brushes) and cover a given contact area. It's viscosity allows it to "stay put" with a careful and modest application. If your MSA Graphene does much in the same way, that's a very good thing. I look forward to trying it in the near future.
Thanks for the back-and-forth. I've heard nothing but good about your products here on this forum. Carry on, good Sir.
Viscosity - Correct; I've found that connections I left for a month or so, when you pull the plug it looks pretty much like it did when you put it in. Also, I don't think it will dry up, at least not quickly, as the base is not very volatile.
Regarding what's going on at a microscopic level : One of the main reasons I think this works so well is due to the particle sizes.
Compare these figures:
Nano-silver : typical particle size ~100-500nanometers , surface area per gram ~1 square meter per gram
Graphene (of the types used in GCE) : particle size ~5-20nanometers, surface area per gram 60-100 square meters per gram.
My best idea of what's going on is that these ultra-small particles are good at getting in between metal conductors, to 'fill in the gaps' left by the inevitable micro-level roughness of the conductors. But regardless of what is happening at the micro-level, the important thing is the subjective improvement that occurs.
Question-Do you think it would be beneficial to "rough up" the metal connectors more like with sandpaper prior to application? BTW,I have a 2ml sample coming to me from you so I just wanted your thoughts on this
One of the stated reasons for the ability of these contact enhancers to work is that they fill up micro gaps in the metal and create more surface contact. Roughing it up would likely be the opposite of what you would want to do. T456

I wouldn't rough it up. Even if it was finely polished to our eyes, at a microscopic level it's pretty uneven.
I upgraded my outdoor Grounding Rod System with a larger gauge wire a few years ago and it made a very nice sonic improvement, mainly a lower noise floor...
I took in the Grounding Rod Clamp to Home Depot to find the larger AWG size .
I think it was a 8 AWG or a 6 AWG...
I used MSA Graphene Contact Enhancer on both ends of the outdoor Grounding Rod Wire...
Wonderful results seen in both Audio and Video...
