Bioplastics: Water resistant Casein Glue. Milk glue.

Using a formula I found in the book linked below, I make a water resistant glue that has been around for hundreds of years. This formula has been used in aircraft, boats, and is still used in exterior plywood. Selected for superior bonding strength over Urea-Resin glue.
The book on this and other Casein glues, paints and adhesives are found: archive.org/details/caseinits...
At GEO-sustainable, we formulate everything using sustainable materials to make bioplastics, solar panels and supercapacitors.

You are a genius man. ❤️

[@GEOsustainable]

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

[@mrcmountain6342]

Great, thanks for the book-link also!

[@GEOsustainable]

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

[@zakhoskins6404]

Wow, great find. I've seen tons of beginner level recipes for various bioplastics and such that aren't waterproof (or at least resistant) plastered all over the internet, usually in the form of annoying listicles. This is by far the in depth reference I was hoping for. I look forward to trying some of these recipes out. Much obliged, and subbed.

[@GEOsustainable]

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

[@ImranMalik-dl7wg]

It's really handy. Thanks for your expertise Sir.

[@ImranMalik-dl7wg]

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

[@GEOsustainable]

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

Thank you for this wonderful and informative video. Can this adhesive be used for paper to stick on metal surfaces? Will it be brittle after drying and the paper may fall off?

[@GEOsustainable]

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.

[@jomelzorilla1773]

That's very nice and informative video Sir, do u know how to make non-toxic and water based glue for leather bonding?

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.

The production of urea from inorganic raw materials was an important conceptual milestone in chemistry and is considered the birth of biochemistry. This synthesis showed that a metabolic product can be produced in the laboratory without biological raw materials, and ultimately led to the fall of the theory of vitalism.

[@GEOsustainable]

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

[@GEOsustainable]

Correction. The theory of nonviltalism;)

[@randymarcellus9260]

Well, this is surely the most useful video I've found about casein glue! One question, has any heating been applied to your process when stirring the ingredients for the WBUC formulation? Maybe on the hotplate magnetic mixer, or using warm water instead?? 'Cause I've tried that recipe myself and I was only able to get a sticky-but-too-watery solution, that remained liquid for days... I was wondering what could gone wrong (seems that urea didn't stirred as intended, some traces remained in the bottom... )

[@GEOsustainable]

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.

[@randymarcellus9260]

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

[@miss.butterfly6745]

How many hours was it mixed for? What can i use to thicken the glue during application before it actually dries?

[@GEOsustainable]

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

[@dianes3658]

Hello Sir, I am so glad I found you. Could you please tell me if this would work with yarn and dry hard to make a lamp globe?

[@vdvbert]

Nice video sir, it contains so much information. I also liked the link to the book which I downloaded immediately for further reading. I have some questions, you mentioned your own recipe (3th mixture) is waterproof and stays hard. But this hard, is it brittle or still flexible? And if its brittle, will adding glycerine it to become less brittle or do u have other suggestions? i want to use it as a leather-glue but its has to be flexible. thx

[@GEOsustainable]

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.

Hello, this is really interesting, i am working on biodegradable material as a sustainable "fabric" for fashion, but biodegradable material is soluble in water and therefore i wanted to coat the biomaterial with a bio substance that is water resistent. This video was really inspiring but what would you use of water resistant coating for clothing which needs to be flexible and bio-based?

[@GEOsustainable]

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.

[@siwlindblad7383]

Thank you so much for your help!

[@CeeKayz0rz]

Is this food-safe with the addition of urea? Trying to make a food-safe glue that I can run into a cracked ceramic coffee mug (basically, immersion in the heated glue for time to allow it to flow into the crack, then removal, cleaning, and curing)... I think casein may be my ticket to this. I've found another recipe that calls for casein, sodium hydroxide, and calcium hydroxide, but unfortunately it is not a "waterproof" glue, but a "water resistant" glue, meaning use will most likely see it ultimately fail eventually (tho, another batch and application isn't the end of the world)....

[@GEOsustainable]

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

Hey great video! very informative. I have a few questions for a project I'm working on, hope you can answer some of them (: 1) what materials do you recommend using to make this glue non-toxic but still water-resistant? 2) do you know if this glue can be used as a good oxygen barrier? 3) what would you recommend using to make the glue thicker but still keep its qualities? 4) how long do you think it can last in an outdoor environment? thank you!!

[@GEOsustainable]

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.

I have read that the Mosquito aircraft was not suitable for use in the tropics as the glue used [was it casein?] did not stand up to the humidity.

[@GEOsustainable]

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.

[@adoreslaurel]

@@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.

[@GEOsustainable]

@@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.

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.

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

[@ziongite]

Ammonia can be gained cheaply. Obviously water is cheap. Borax is cheap. Buying Casein itself isn't cheap, however you can get milk cheaply and there are common methods to extract the casein. With all this considered, it means you can make decent amount of glue for a very cheap price. Because store bough glue in large quantities, that is water resistant is expensive.
