Bioplastics: Water resistant Casein Glue. Milk glue. 

You are too kind sir. I am happy you found value in the video. Thank you.

My pleasure. It is worth trying just...everything in that book. Enjoy!

I have reformulated this a bit. I add Sodium Flouride to give it even more water resistance.

Is it suitable for scouring pad and foam solid joints. Please advise

I don't think so. But, it never hurts to try and see what

Glad you liked. I hope you become a regular.

Great to hear. I hope you try it out.

That is best to answer in an email. My email is martin20krunner@yahoo.com

I have a video to help you with your questions here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-g3wTriZiXOg.html

2 if I remember correctly. If you want to try this, just do like I do....keep an eye on it.

Glad you liked it.

Yes, absolutely. You have a great idea.

I would not consider it suitable.

Thank you Sir, much appreciated.

Yes, I think it will stick to metal. Wood to wood, paper to paper is fine. I would be willing to try metal to metal. Give it a try, lay it on thick. Heat it in an oven at 200F for a few hours. Never tried wood to metal. I am building a greenhouse right now and I am using this formula. Check it out.

Sorry to say, milk glue for ceramics, glass, and pottery are a myth. This formula is not waterproof, it is water resistant.

I have included a link to a free book I get many of my recipes from. I am sure there is something in it for you. Check it out. It is in the description of several of my bioplastic videos.

I did not heat. I only recorded the room temperature. It takes from 2 to 24 hours to mix, depending on how it clumps when it goes in water. I would say, give it more time to mix.

@@GEOsustainable I'll keep trying. Many thanks again for sharing this!

I am sure this formula can be added to milk paint.

Once again, I explain all of these questions in the video. I am afraid you have to watch the video. Not ask questions of me to save you time.

You need to use something called Hyde Glue, or Hide glue. It is waterproof and made from animal hide, and most certainly ideal for leather.

Yarn once was made from milk. Milk yarn dresses were popular and still a much sought after item on eBay. The yarn was manufactured in Italy. Look into QMilch, I think they are making it now. I haven't found a natural way to waterproof milk plastic, but milk yarn is processed similar to how rayon yarn is made. Rayon manufacture is so environmentally damaging, it is banned from manufacture in the US. Early days of Rayon fabric required it to be Dry Cleaned because Rayon wasn't waterproof. Whatever they did to do that is the same thing you will need for your yarn. Look up Viscose Rayon. Milk yarn sounds cool, but making it is not so cool. If you find a way to naturally waterproof milk plastic, let us know. That is the Holy Grail of bioplastics. In my opinion, bioplastic doesn't suit every application, but we would be wise to use it where we can and reduce items made from natural gas.

Thank you so much for your help!

This formula is only water resistant and has some issues with durability. I have another formula coming soon that should give longer lasting results. If you are in a hurry, email me and I will give you the formula, as it is too much to put here.

I don't know. This formula is not waterproof, it is water resistant.

@@GEOsustainable ok thank you so much

urea-formaldehyde

@@GEOsustainable thanksss!!!

Which may give rise to a theory of Inviltalism. :)

Correction. The theory of nonviltalism;)

Hi sir I have to ask question.i made wood white glue from pva+wheat flour+tio+ptf May I use your formula .borex.urea.casein. into my formula to be made Strong my glue and dry fast.or you have any suggestions for my formula to make strong and dry time fast

You found it. Is this video I make a water resistant glue. Water proof would require Formaldehyde...not something you want to put in your mouth. Examine your task...you want to make a 1-use plastic, it does not need to last for more than 1 hour. Vinegar makes Casein more insoluble. Bioplastics are best suited for 1-use, ideal for tableware. If you need, you can introduce a second step. Coat your plastic with Shellac, then it will last much longer.

@@GEOsustainable Thank you sir

@@GEOsustainable hi

I have just what you are looking for here. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6WNHoKeFQUU.html

Yes, it is used to make plywood. Some older airplanes use this glue formula. Hope you get a lot of use from it.

Great question. I have a series on Casein and the different ways to use it. I use vinegar in many of them.

Yes, of course you may. Get comfortable, it will take a few hours.

1) This formula cannot be made NON toxic. Use a HYDE or a PVA glue. 2) It is an amazing oxygen barrier. Superior to plastic. 3) Use more Casein. 4) 2 weeks if fully exposed in gentle weather. And this also depends on what has been glued. It can be permanent on wood, metal and glass.

@@GEOsustainable thank you so much for the detailed answer. do you have an idea in mind for a natural material to make this glue or a bioplastic waterproof?

Hi sir Can u suggest me for inner layer coating for biodegradable bottles for water

Not usre what you are asking. You can buy Urea online.

After following through the chats, urea was sourced from cow urine.

Namaste.

Your suggestions are valuable for me... !! Please guide

About 40C, if I remember. Just warm it a bit, without boiling.

Thank you for your question and your kind words. This video is more about the book that I refer to in the link posted in the description below. I encourage you to read the book, as it contains all the formula I make. Here is the link, and good research. The book on this and other waterproof Casein glues, paints and adhesives are found: @t

I had to look it up. I knew Casein was and is still used in aircraft and boats, as well as exterior plywood. No other glue in existence can beat Casein bonding strength. Very high humidity can soften the glue, but will regain it's bond strength as soon as it drys. I have flown in the Mosquito reconnaissance in Vietnam. Those babies are fast, fast and super agile.

@@GEOsustainable I worked after school in the 50's in a caravan factory and they used something called urea formaldehyde, no idea what it contained., Why would it be superior to Aqudhere {?} or Bondcrete, PVA based glue, when PVA dries on your clothing it's like water based paint, impossible to soak out.

@@adoreslaurel The reason I choose this type of glue are the Formaldehyde is rather nasty stuff and PVA is made from oil. It's a personal choice.

@@GEOsustainable Very interesting, Thanks for that.

Casein is powdered milk. It will not damage your lungs, but if you inhale a lot you can reach a point of respiratory distress. Wear a dust mask to be safe.

You have come to the right place.

I have never tried. I think it would work if it is plain.

Did you watch the entire video? Because, I tested it in front of the camera.

I will let you know in a year. You saw me make the first batch of this. Refer to what I say at 17:25

One year later, and after continuing to work with this, I can say this is ideal solution for one use plastic.

That sounds like a great idea. Stay tuned, I have a bioplastic using Casein video in the works.

Cool, extrudable casein could be 3d printed now that they have come up with the printers that print out clay into artistic and structural parts. One woman on RU-vid has come up with a recipe for cement clay.

My pleasure. Casein, Borax, Urea, Vinegar, water are the list of ingredients.

Thanks

All good stuff. Agree.
