Video is not clear but one thing I want to ask. for spray painting for, one use Malamine for shining and Hydrophobic but Malamine is Costly. whether it can give shining?
Yes hydrophobic coating can be applied on solar panels, but it will have different composition. Please search the literature for appropriate coating for solar panels.
There is no boiling involved, white thing is magnetic bead, it is required to stir the mixture of vacuum grease and the solvent that is hexane in this case.
Here I used n-hexane. This is just a tutorial video. If you are doing research, then I suggest you do a thorough literature search and then chose the appropriate chemicals.
hi, i'm indonesian. what's others name or product for silicone grease? and n-hexane. difficult for me to found in my country. can i just buy to checmical store. or do you have any others suggestion ? thanks
@@WorldofNanotechnology are there any other natural alternatives for silicone sealant and paint thinner? like extracts from plants etc that we can use that will have the same result as this spray
@@baishahannahbalayanan7404 Yes, there are many chemicals obtained from natural sources, which can be used to create hydrophobic surfaces.

congrats on the channel content. I would like to know if there is a way to make a waterproofing agent that can be used on cement or if fumed silica has this use? how is it made? thanks
World of Nanotechnology just finished doing this with silicone sealant and paint thinner, it worked. Thank you so much. however, the solution can no longer be used the next day because it's sticky already, how can I rid of that? thanks
Hi, my name is Kevin, I am from Indonesia. I am so interested in making hydrophobic spray for shoes, bags, and caps, and just now I happened to watch your video on RUclips on how to make one. So my question is, is it possible to replace the silicone grease with silicone oil/silicone liquid?
@@WorldofNanotechnology well pdms (polydimethylsiloxane) is another name of "Dimethicone", this is one type of silicone oil. but, may be you have to concern what type viscosity of Dimethicone do you want to use
It will not be like a clear solution but slightly hazy. Please check the ingredient of silicone sealant, it must contain polydimethoxysilane (PDMS) then only it will work. You may try adding a little more paint thinner.
@@hariprasanth952 silicon dioxide is not hydrophobic. You will have to prepare alkyl functionalized SiO2. You can do it by reacting methyl trimethoxy silane with TEOS.
@@inkkaheart This process is not applicable for wearable fabric. You need a solvent which can be easily evaporated. Also the silane precursor. which is used for wearable fabric is different.
@@WorldofNanotechnology Depends on the relative ratios. The Rain-X automotive glass solution is a small bit of silicone in like 97% isopropyl alcohol, the starting solution of alcohol must be practically anhydrous or free of water. I use 90% isopropyl and paper towels to wipe silicone glue off my hands clean all the time.
There are many companies who sells these chemicals. One such company is Wacker chemicals. You can purchase the concentrate and dilute according to the need.
Depends on solvent, if you use paint thinner, it smells like gasoline, if you are using alcohol based solvent in some other methods, it will be like alcohol
@@xavierbaniels3176 alcohol based solvent like isopropanol is for another method. The method shown in video is for educational purpose only. For car paint formulation is different. I suggest you to read literature if you want to make it your self
How can we prepare a superhydrophobic solution from Tetraethylorthosilicate and methyltrimethoxysilane wich has isopropanol as solvent. Is there a book which can introduce us to the chemistry of superhydrophobic materials and spray?
What's the ratio of tetraethyl orthosilicate and methyltrimethoxy silane to be mixed with isopropanol to obtain a superhydrophobic solution? I'm itching for the response.
Hi sir, We are going to start a care care products company , it's a small startup How can I get hydrophobic solution formula? We need to make hydrophobic windshield cleaner, hydrophobic Tyre polish, hydrophobic dashboard polish, Is it possible to make hydrophobic polish and cleaner? How can I contact you sir ?

Will dust or dirt stick on the surface more easily (will it make the surface sticky)
Can you please tell what was the thing you put in the beaker after the n hexane? The solid one
That is a magnetic bead for stirring.
Can it used on car windshield..? Have u tasted on glass.?
Hi.. can I make mist out of this solution ... Co I need to experiment on my jewelry design
I don't know how hydrophobic spray can help in jewellery. You can try using the solution in a spray bottle. Or simply buy spray solution from Amazon
after washing the cloth, will it retains the hydrophobic property or any loss in performance ?
There are other hydrophobic solutions which you can use for textile, check the website of Wacker chemicals
@@WorldofNanotechnology thanks
can you say what you last entered (solid white stuff) because I can't understand what you're talking about
You can use silicone sealant which can be purchased in hardware store. Mix it with paint thinner.
Show us how to make car nano ceramic coatings
was it 1gr of silicone sealant and 25 ml of the solvent either ( n-hexane or paint thinner ) was that correct?
Yes you can try that ratio. Paint thinner works better.
Can you tell which research paper you referred to?
ninithi.wordpress.com/2015/07/27/make-your-own-ultra-ever-drynever-wet-at-home-here-is-how/
I really liked the video but missing out on the material used to make the soln (not clear)
We used polydimethyl siloxane which is present in vacuum grease.
Video is not clear but one thing I want to ask. for spray painting for, one use Malamine for shining and Hydrophobic but Malamine is Costly. whether it can give shining?
Hello, can I apply the prepared hydrophobic solution described in your video on solar panels?
Yes hydrophobic coating can be applied on solar panels, but it will have different composition. Please search the literature for appropriate coating for solar panels.
can Kerosene be used as the solvent?
Yes you can use kerosene oil
What can be alternative of silicon Grease that you uesd
silicone sealant, you can purchase it from any hardware store.
@@WorldofNanotechnology thankyou
Familiar with the zoom function on a phone? It's pretty easy to use. It allows folks to see ANYTHING YOU MAY NEED US TO SEE UP CLOSE
hi can any silane be good here. As i have trimethoxymethyl silane. will it work? i wanted to make hydrophobic glass for an experiment
Yes methyl trimethoxy silane will also work
hello, what is the white cube that you put in into when you are boiling it???
can you reply me as fastest as possible. thank you so much.
There is no boiling involved, white thing is magnetic bead, it is required to stir the mixture of vacuum grease and the solvent that is hexane in this case.
Which solvent did you use and the concrete of this solvent???
You can use turpentine oil, 1 wt percent solution
@@WorldofNanotechnology can you please write the operation description it will be very useful to me
@@honda2213 Brief description is already given
I am also working on superhydrophobic surface I want to know that what type of hexane you used here???
Here I used n-hexane. This is just a tutorial video. If you are doing research, then I suggest you do a thorough literature search and then chose the appropriate chemicals.
@@WorldofNanotechnology ok...how can I contact you....??
What was the white solution you put in before stirring in 1:01
It is not solution, it is magnetic bead for stirring.
Nice to see amitians doing the job . Well Done. Lab has improved so much now for sure !!
It was high time for Amity Institute of Nanotechnology to create more awareness about the beauty of nanotechnology
hi, i'm indonesian. what's others name or product for silicone grease? and n-hexane. difficult for me to found in my country.
can i just buy to checmical store. or do you have any others suggestion ? thanks
You can use silicone sealant which is used in plumbing work, and use paint thinner as solvent
Please write your feedback and subscribe to my channel. If you want to see any particular experiment then please write in comments.
Hello I'm from the Philippines and I was so amazed at hydrophobic. Can I ask what is the ratio between silicone grease and hexane? Thank you so much
Have you found the answer? I want to try this experiment
@@idontrte Not yet
Is it applicable to ordinary paper? Or in a paper made from a fabric? Thanks
Yes, you can spray on ordinary paper
@@WorldofNanotechnology are there any other natural alternatives for silicone sealant and paint thinner? like extracts from plants etc that we can use that will have the same result as this spray

Okayy I got it thankss. Lastly, is your solution odorless?
@@baishahannahbalayanan7404 Solution has the odour of the solvent
congrats on the channel content. I would like to know if there is a way to make a waterproofing agent that can be used on cement or if fumed silica has this use? how is it made? thanks
Thank you so much! Please comment raw materials for hydrophobic spray. Thanks
What was the temperature during stirrering???
It was done at room temperature
@@WorldofNanotechnology I mean I want to know wht was the temperature of hot plate ??
@@tejasvinisingh2003 Yes we only used the hot plate for stirring, we didn't heat it. So it's room temperature.
@@WorldofNanotechnology ok....thank you
How about Fabric Coating Hydrophobic? Thankyou sir :)
can i know for how long this hydrophobic shelf life and how much each substance is
You take 1g of silicone vacuum grease and 25 ml of paint thinner and mix them well
You can also use silicone sealant which is used in homes
Can you give your contact no for research activities
Please reply asap.. i want some knowledge on some chemicals
Hi , can i just use silicone oil instead silicone sealent?
No, silicone oil does not have methyl groups, you can use polydimethylsiloxane
@@WorldofNanotechnology hi , appreciate your answer. So silicone sealent with ethyl acetate or ethanol will work yes?
@@ariefliem1777 no silicone sealant will not dissolve in polar solvents, you will need non-polar solvent
@@WorldofNanotechnology it will dissolve use homogenizer no?
@@WorldofNanotechnology What can be the solvent for Polydimethylsiloxane
Hello dear, I hope you are well. What book do you recommend to read on the subject?
Does it work on latex material...?
I don't know. I only tested on cotton fabric and glass.
@@WorldofNanotechnology ok ....no prob...I'll find it out...
Thank you...🙏
Great video!! Would be great if you can show Oleophobic solution!!!
Is coating dielectric?
Halo sir
What material can i use for make carnauba wax to be liquid at room temperature?
Thx..
Great vedio i want some more information
Can i use it for eyeglasses ??
No, you better buy commercial hydrophobic spray for glass
can I use silicone sealant instead of silicone grease or vacuum seal grease for this hydrophobic solution?
Yes it is the same, silicone sealant has the same chemicals, you can check it's components, if it contains dimethylsiloxane then it will work.
World of Nanotechnology just finished doing this with silicone sealant and paint thinner, it worked. Thank you so much. however, the solution can no longer be used the next day because it's sticky already, how can I rid of that? thanks
@@rhiannemendoza9466 you have to keep it in air tight bottle, otherwise solvent evaporates. Simply add more solvent and stir. It will be ready to use.
Hi. How did it auto stir???? What tab did u put in?
What can be done by paint thinner* that you mentioned?
I didn't mention any painkiller. This video is about hydrophobic spray solution.
@@WorldofNanotechnology
Do you have any idea about making hydrophobic spray by car lacquer spray and deodorant?
@@hooriarizwan4174 no, I have not worked with that, you can search the literature about that
@@WorldofNanotechnology
Oh okay, I've been trying it with wax and car sprays but couldn't find the right thing.... I'll try this now thanks
hi, may i know if i mixed this solution to powder by spraying it , will it turn into hydrophobic powder for dry coating?
Hi, my name is Kevin, I am from Indonesia. I am so interested in making hydrophobic spray for shoes, bags, and caps, and just now I happened to watch your video on RUclips on how to make one. So my question is, is it possible to replace the silicone grease with silicone oil/silicone liquid?
No silicone oil has entirely different property, you have to use the ingredients present in silicone grease like poly dimethylsiloxane
@@WorldofNanotechnology well pdms (polydimethylsiloxane) is another name of "Dimethicone", this is one type of silicone oil. but, may be you have to concern what type viscosity of Dimethicone do you want to use
@setia bakti bang ada instagram ga ? Mau tanya2 boleh ?
Superb experimental video.... Proud of you both....
Hi sir, can this protect against rust?
It is inherent property of hydrophobic surface to protect against rust. If you coat the surface properly, then it will act as anti-rust
@@WorldofNanotechnology thank you sir
Hi.. i used clear silicone sealant and paint thinner(MTO) but silicone is not getting dissolved in it after 30 mins of agitation
It will not be like a clear solution but slightly hazy. Please check the ingredient of silicone sealant, it must contain polydimethoxysilane (PDMS) then only it will work. You may try adding a little more paint thinner.
Can i use silicon dioxide power instead of silicon sealant ??
@@hariprasanth952 silicon dioxide is not hydrophobic. You will have to prepare alkyl functionalized SiO2. You can do it by reacting methyl trimethoxy silane with TEOS.
@@WorldofNanotechnology is this process could be also used for fabric? Will this be less harmful as this is not using solvent like paint thinner?
@@inkkaheart This process is not applicable for wearable fabric. You need a solvent which can be easily evaporated. Also the silane precursor. which is used for wearable fabric is different.
How to remove hydrophobic coating?
Kudos to both of you! my query is sir and madam : is this solution when applied on glass will it still work please advise
The formulation for glass is different. Email me k_ranjit@yahoo.co.uk
In video name not clear please tell me full name of this material
Check the details of the video, process is given. It is called silicone sealant.
Hi,
This is mayur
I wanted to get in touch with you
Thank you.
pure Isopropyl alcohol is a less toxic solvent and will also dissolve silicone grease
Definitely isopropyl alcohol is non-toxic solvent. But silicone grease was only partially soluble. But it can be used.
@@WorldofNanotechnology Depends on the relative ratios. The Rain-X automotive glass solution is a small bit of silicone in like 97% isopropyl alcohol, the starting solution of alcohol must be practically anhydrous or free of water.

You are Doing good Work. Thankyou For this Video. 😀
I only ask you one Question -
I want this Chemical in Big Amount How can I get ?
There are many companies who sells these chemicals. One such company is Wacker chemicals. You can purchase the concentrate and dilute according to the need.
I want to know Can it be used on Car Windshield (Car Glass).....And How to keep the solution "Ready to use for Longer Time"
No it will not work on car windshield, they have different composition, you can purchase from amazon
@@WorldofNanotechnology can I have ur email Id pls
@@gauravnaik2525 email id is given in experiments details
Is this resistant to scratches?
SiO2 provides some scratch resistance. But that is a different coating which is used to prevent scratch in cars.
Hi! This is very cool. Is there any way to make it bio based or Biodegradable?
This is not biodegradable, search literature for that
Can we use it in car coating
This is just for educational purpose. For using hydrophobic coating in car the formulation is different.
@@WorldofNanotechnology so how can we make it?
What proportion did you use?
1:25 wt/wt ratio of silicone sealant and solvent
That was really interesting! Thank you!
Is this the same thing called 9H?
I do not know the composition of 9H. It may have similar constituents.
Which solution you put inside
I mixed silicone sealant with hexane. You can try with silicone sealant in paint thinner also.
What other alt can i use instead of silicone grease please update me asap!!(i have to submit my project tommorow)
Silicone sealant used in homes, you can find in any hardware shop, mix it with paint thinner
@@WorldofNanotechnology thankyou so much💕
0:34 i cant hear it clearly, name the chemical pls?
@@goodday1314 the liquid in the bottle is called Hexane
What is the life for hydrophobic coating
This is just an educational video, life of coating was not tested
Whare i purchase that thinks bro..
The product can be purchased from online stores like Amazon. If you want to make your own, you can purchase the ingredients and make.
What will it cost to do at home
The cost of silicone sealant and paint thinner can be found out from local hardware store.
What r the meterial pls tell me theory voice not clear
For how much period does this coating last for ?
This coating was not tested for durability, but any hydrophobic coatings specially the commercial spray has long life of more than 30 days
How Does It Smell?
Depends on solvent, if you use paint thinner, it smells like gasoline, if you are using alcohol based solvent in some other methods, it will be like alcohol
Can I add some scent to it? I never heard of alcohol-based paint thinner. Can you give me 1 example, sir?@@WorldofNanotechnology
Can i Also Use it on Car paint sir? nice expirement btw
@@xavierbaniels3176 alcohol based solvent like isopropanol is for another method. The method shown in video is for educational purpose only. For car paint formulation is different. I suggest you to read literature if you want to make it your self

World of Nanotechnology thank you so much sir
does this hydrophobic coating work on metal surface??
the same question does its work on aluminum?
Nice one ...
Is this Oileophobic?
No, it is oleophilic. Anything which is hydrophobic will be oleophilic.
@@WorldofNanotechnology thank you for your valuable time for quick reply... This is useful for my project work... Keep guiding us....
Use in release agent composition
Thanks so much! The solution worked so effectively and amazed everyone with the results! 🥳
You're welcome!
Great job!
Bro i tried this but it's not working
Plz tell me more about this
Did you try with silicone sealant and paint thinner. You can purchase silicone sealant from hardware store.
Yes I use silicon gel and hexane
@@deepsohal8811 it worked for me. You can also try wax in paint thinner. There are many literature. Read them.
