- The epoxy conductive ink video is made on request! I take the time to give you some idea about conductive ink based on epoxy.
You need to play with the total amounts of graphite, binder, etc...

when you burnish the surface.... and the resistance goes down, it might more be related to surface conductivity because you have exposed graphite that previously is coated with non-conductive epoxy. An important question is what is the conductivity "through" the epoxy-graphite matrix. If you painted this onto a current collector, you might get a different result if measured between the current collector and the surface of the matrix. Just a suggestion :) Take care... Doug
I remember ol mate kev said the key was to use large flake graphite for less than 10 ohms
Yes and no,.... there are mixed thinking about this. Someone like to use small size particels anotherone love to use larger flake.
I use this setup when I was making a carbon fiber board. Graphite speeds up the cure really fast so keep that in mind.
When mixing epoxy its always better to follow the instructions. If the mix says 10:60 and you want half measures its 5 parts part A to 30 parts part B i.e. 5g Part A and 30g Part B NOT 6g Part B as you keep saying.
If you take a closer look around 1:25 you'll see that he is using the correct ratio, which is 100:60 A:B, so 10gr A and 6gr B is correct.
This reminds me of electret where voltage is applied while it is drying and then will hold the charge...
Thank you for making this video!! The idea was not so bad I guess :) the resistance on your mix was much better then on my attempt, I tbink mixing in acetone made graphite distribution in a mix much more regular!!
Instablaster
Thiners + Grafito en polvo (usado para lubricar sistemas mecánicos de cerrajería, llaves).
Mezcla Thiners + Grafito y mientras lo bates llegará un punto en que se une todo...comienza a fraguarse la mezcla y es tiempo de utilizarla antes de que seque totalmente. Una vez seca, aún agregando + Thiners no sirve a modo de pegamento hasta tanto le agregues nuevamente más grafito...
PDT: Sólo lo pude realizar con Grafito en polvo (talco), con mayor granulometría no produce homogenización. Sirve incluso para pintar sobre nylon.

hi good work --can you roll it in press or like carbonator put it in t-shirt press heated? test the ohm then
Good idea.
Good idea for diy projects
What do you use the graphite conductive paint for?
You have quite a few applications. Electroplating, haeting, sensors, touch switches, battery conductive additive, simple circuits,....
@@cayrex Thank you
good to see you making vids based on requests
When I get many requests about something and if I have time, then I try to make a video on the request topic.
Also this video is around 1 month old like several others videos which are on pause,... because I dont get the time to editing 😓
Sir tell me the name of device which you are using to measure the conductivity of ink
I've been trying to make conductive epoxy, but for some reason, no matter how much graphite I add it remains, unconductive, any recommendations at all?
Nice ..I am doing this with CNTs
A little expensive but the performance is definitely better
@@thiyagarajreddy On PET,... no. The size is
I feel the way forward with epoxy is to coat the paper first very thin with epoxy and the drag it through a tray of graphite powder. Only a very fine top layer of graphite will stick and now let the glue set before burnishing
Are we letting the acetone evaporate?
Yes
it works also with nail polish (instead of epoxy)
In basic, yes you can.
👋 Hi, awesome video.
What’s the acetone for ? Does the acetone affect the electrical resistance ?
Thanks! Acetone is the solvent to dilute the epoxy. When the paint is dry,... meand that the acetone was 100% evaporated.
@@cayrex THx u so much
Can I use this epoxy Conductive Inks on FRP or silicone rubber substrate??
Please give me something idea.
Nice work. Was the conductivity as good as the ink you made for the heaters.
Maybe a few drops of SBR would give it more flexibility :-) Martin.
You have also some flexible epoxy but this epoxy I have at home that way I use this one. No, the conductiviti on this one was not so good like I get on my ink.
Great video
I was wondering if rubber cement could be made conductive.
Yes,.... but the question is what will be the resistance
what is the epoxy made up of ?
Why not press it on ,20 tons, connect your lead then epoxy over it.
if you paint it on blank printer sticker paper, you could cut our feet for remote control repairs.
Can I ask what is your best battery yet.
Hmm hard to say,..... I have several types which can say that are the "best". For example: one have good stabilty and is safe, other have good capacity, third is cheap to make,.... so in this case is hard to say which is the best
So do you copy Robert M. Smith or does he copy you?
Heh,... no one copied. The basic of making inks is really good known. For each ink you need solvent, binder and active material (except conductive dry ink 😉) . Then you have additives, material rates and the making process which can be different. The material selection is also different. So,... if you was thinking about the copy of the concept of conductve ink,.... the conductive ink concept is also known for reall good time now.
Maybe you can call it resistive ink 🤗
Hehehehehe yes! In basic is good because the resistance is lower that 100 ohms, but I am used to make inks with lower resistance 😊☺️😉
@@cayrex but for heating panel what is best. 50 ohms?
@@Buzzhumma depending on what power you want and what voltage you will use.
@@cayrex ah yes. Made to order. 👍 I do wonder if there is a sweet spot in effeciency in respect to lower dc voltage and higher ac voltages?! Any thoughts as from what I imagine the current is doing the work either way but in respect to migration of electron s I would think maybe the higher voltage would experience less resistance and therefor more effecient?

Young man, I'm not trying to rain on your parade, but you were just guessing all along on your weights. Heck you should have put your graphite powder in and then mixed the two part epoxy and then added the acetone as a thinner. How did you think your weights were right after leaving the glass stir stick inside the cup? Just not proper lab work. Just my opinion. It doesn't count for much.
Nothing wrong with some constructive criticism, but better make sure you get things right...
The title nor he says that this is the way to do it, better yet if you had listened to him around 0:32 and 1:43 you would've heard him say "try" and "something like this."
Why should he mix it in the order you think is right? Mixing Part A with acetone makes it easier to thoroughly mix the graphite, and since there's no Part B in the mixture yet, you can take it easy as it won't cure, maybe it's not a bad idea to get the consistency right first?
Leaving the stir stick in doesn't matter, you could even stick an elephant in there if the cup was big enough and the scale was up to the task, the mixture + a 4 ton elephant + 5gr is the same as the elephant isn't part of the mixture, yeah sure you couldn't mix things well (or at all), but I hope you get the point, not to mention that he zero's the scale every time.
It's just a video (on request) to show what you'd need and how you could do it, depending on your needs you could change the recipe.
But the watchers always know better than the doers...
Maybe watch the video again next time, and possibly make notes, before you comment?
