Making Inks And Paints - The Basics

[@seankelly1291]

I just want you to know, you are one of my very few living hero’s. Because you share your knowledge so freely. Also, I love what you’re currently doing with the battery company.

[@ThinkingandTinkering]

thank you mate and thank you for taking the time to say so - cheers

[@nate8334]

Thank you for making these videos. You are very knowelageble and present the information in a way that really helps with understanding the subject for someone who wants to apply it to a project. I've been enjoying your videos about coil windings a lot.

[@tcoo1999]

Can't get enough of your videos just now Robert. They are a great resource for the hobbyist tinkerer! Thanks for sharing your knowledge! This was a great summary of the ink/paint making process. I'm off to look for your book! :)

[@ThinkingandTinkering]

cheers mate

Hi Rob, I know this is old, but still informative. Shouldn't the comment about surfactants be part of the carrier discussion? I.e. you can use water as a carrier for many otherwise impossible applications like plastics, by adding appropriate surfactants.

Congrats on the new lab! Once again thanks for the open source info!

[@codedesigns9284]

This is an older video now, but we’re still catching up. Have you looked at other materials to add to the ink that may be more conductive, especially as it relates to newer videos and the triboelectric nano generator? Excellent video, you are an excellent teacher. 😊

[@TheRealHolyGhost]

Great stuff Robert. Have you considered using a lapel microphone? Since you have moved your operations into the lab the sound echo's and is more difficult for me to hear clearly.

[@mannytuzman3461]

How about a rubberized graphene roof paint???????? Mix graphene with a silicon or similar paint. Will it work if I just mix graphene in the paint? Please tell me?

[@jonitortian8484]

Great work Robert. I am looking for a flexible conductive coating to use over polyurethane rubber materials to act as an electric field screen or deflector in high voltage apparatus. The paint doesn't need to carry currents, 1k Ohms/sq will do the job. The primary objective, the paint shall adhere to the polyurethane and does not crack or flake off as the rubber base material deforms. I have tried to add 40ml of Xylene to 17g of a polyurethane sealant/adhesive and 25g of graphite powder, the outcome was satisfactory but not that good as I wanted it to be, minor cracks appears as I fold the substrate material but the paint itself doesn't fall off. The surface resistance is about 700 Ohms/sq. Do you have any opinion on the system I have used to improve it, or do you recommend and alternative solution to use on polyurethane rubber.

[@ThinkingandTinkering]

I am sorry I am afraid i don't really

[@nanatv1507]

Can anyone tell me what is the most commonly used binder mentioned in the 7:13 min video? I didn't quite catch the name. Thank you!!

[@pooptv3210]

..im here seeking the same 😔

[@pooptv3210]

AlKyd!! Thanks to @teslar1 from the earlier comments 🏆

[@AimanNazri]

How could I determine the curing time and temperature of the ink, it would be better if you could explain with example. Thanks

[@ladyofmorgana380]

Thanks for making this video, i learned a lot about making ink/paint. I was wondering, could you make a video on how to make a writing ink (to be used in dip or fountain pens)?

[@ThinkingandTinkering]

of course - will do

[@JasonMasters]

I remember Orson Scott Card (he of Ender's Game fame) mentioned a very good ink formula in another of his stories (originally called "Hot Sleep" because of the suspended animation process used in the story). The only things I remember are that it used "Blackthorn," a fungus and gum from a tree, mixed into water and boiled for a while then strained through muslin cloth. I've searched the internet to try to find the exact formula but without success. All the links I can find are to printer inks or pens or ready-made ink. There appears to be nothing on how to make ink, or at least the ink I'm interested in. According to the story (and I'm guessing this is factual), the ink will stay black for around a thousand years, and will still be readable after five thousand years (I presume this is with the proviso that the medium it's written on survives that long too). I wish Card had given the name of the fungus and of the tree, and also the correct proportions to mix the ingredients, but such details would probably have detracted from the flow of the story.

[@AimanNazri]

How do you spell that mostly used binder? I can't get what you have said right there.

[@teslar1]

Aiman Nazri linseed oil was the binder mentioned

[@teslar1]

And if your referring to the liquid in the green container. It was called an Alkyd. A typical Alkyd. Would be white spirt

[@pooptv3210]

@@teslar1thank you

[@maheshkpm2004]

do you have any reference or video or book that talks about specific mathematical or chemical equation to understand what specific amount of functional material is needed , what would be best carrier.

[@ThinkingandTinkering]

there are quite a few available just look on google

[@elenitacuchi]

so..what is the best organic binder to print on cotton, in your opinion?

[@ThinkingandTinkering]

really there are loads - have a cast around the net

[@keeganmaloney3440]

I know your busy with your chemistry projects, but what happened to your fusion research? Is that still going somewhere?

[@ThinkingandTinkering]

lol - yes - but you have to prioritize mate

[@blueghost1366]

Could you use aluminum in a powder form as the functional material?

[@ThinkingandTinkering]

yes - but what function do you want? - if it's conductivity it will probably not be that good as the aluminium is bound to be coated with a layer of insulating aluminium oxide

[@blueghost1366]

I wanted to see if I could make a conductive ink using aluminium.How would I remove the oxide?Would making it into a powder form help with the conductivity?

[@ThinkingandTinkering]

Blueghost136 aluminium is very reactive you will need to do more than just remove the coating of oxide - you will need to put an additive in to make sure it doesn't come back

[@jonitortian8484]

No worries!

[@ScottVanKirk]

Great stuff. Thanks!

[@ThinkingandTinkering]

no worries mate

[@ScottVanKirk]

Just curious, do you ever sleep?

[@ThinkingandTinkering]

Scott VanKirk about 4 hours a night lol

[@Allwestconstruction]

Like very much Thanks for taking the time to explain this

[@Khwartz]

05:55 - "linseed oil" (for those like me who are not English tongue and would need like me several watchs to understand what it was ^_^ ) 11:25 - "zinc oxyde" 11:34 - ?? ...-oxyde? (didn't get the first part of name you said ^_^ Can You write it down here please? :) ) 11:47 - "graphite, CAST? (didn't get the full name corresponding to the initials, what is it please? ), graphene" 14:03 - "???, as a table spoon of salt" PS: I remember You that You invite us to replicate and experiment ourselves, so that's Logical we bother You for questions when we don't understand :/

[@ThinkingandTinkering]

linseed oil - it's a standard drying oil for ink manufacture and is used as a binder yes - zinc oxide - it can be an inert filler used just for colour or an active material used in zinc carbon batteries. nickel oxyhydroxide - a component of nickel iron batteries listing conductive fillers as ideas - graphite or carbon naotubes or graphene as examples - there are others nickel oxyhydroxide was the example what you have to remember mate is these are examples of materials from the headings on the board - the actual materials don't really matter - they are just examples of the class of material - so - there are lots and lots of examples - nickel oxyhydroxide is one active material but so it manganese dioxide, lead oxide, lithium iron phosphate - in fact any battery matreial you can think of would come under the heading of active material. so - it is not essential to hear each and every word - what is essential is to understand the guidelines and have a look for you own materials that would come under the headings given in order to create your own system. this is why i am taking the time here - not to list the words for you but to point out you need to get the concept and run with that - then you can experiment for yourself

[@DRSulik]

Atrocious sound quality. Stop recording in an empty ten million gallon oil tank.
