If you add a tiny bit of sodium bicarbonate to the mix, it reacts with the acetic acid and makes it much less smelly. The product of that reaction is water, which effectively catalyses the silicone curing reaction. It ends up curing faster and stiffer but the downside is that the surface ends up a little moist. Good for moulds, not so great for sticking it to things.

Been tinkering on a budget of 0 dollars, so this video just made my day!

[@andrewplant9777]

have made this but did it in a zip lock bag to save getting corn flour everywhere just be careful as the smell of vinegar when you open the bag will make your eyes seriously water

Yeah, I worked for Sugru for 7.5 years as a factory engineer designing/building the machines that pumped/shaped that stuff, I was also involved in mixing the batch ingredients up. I knew Jane very well. Unfortunately, it was always too expensive for most. Obviously, being an employee and an artistic type, I could get access to kilos of the stuff and made lots of arty sculptures with it over the years. The person that invented Oogoo tried to associate it with Sugru and there was some legal shenanigans. The German company TESA bought out the company and the brand several years ago now and Jane has not been officially associated with it for a over a year now. Several years ago Loctite ripped the whole product off, even down to the packaging. Inspite of patents, Sugru could do nothing, Loctite had just tweaked the formula slightly and they got away with it. But Loctite's product simply wasn't the same in terms of it's raw properties and feel. Same with Oogoo. Sugru was/is a much superior product.

This silicone and cornstarch once mixed, will set. How do they keep Sugru from setting?

[@saiello2061]

@@justtinkering6713 It is activated by exposure to moisture in the air. A tiny amount of moisture is inside the packaging, not enough to completely cure it, but enough to give it a shelf life of about 8 months. Shelf life can be doubled/trebled by keeping it in a fridge/freezer. My memory is a bit sketchy on the chemistry but I believe the moisture activates a catalyst which in turn cures the product. I believe it was this moisture activated catalyst that was the chemical innovation needed to allow it to become a commercial product.

[@judyofthewoods]

@@saiello2061 that stickiness was one of the things that attracted me to Sugru. I was able to attach a handle to a stainless steel flask with a couple of small blobs of Sugru. Very useful stuff, if only it wasn't for the price. Oogoo has its place in less demanding situations.

[@skampp]

I use this with high temperature permatex gasket maker. I have a mold that's the shape of my heating block on my 3D printer. So the result is that I make a sleeve for the heating block to dampen the cooling effect from the part cooling fans. Works a charm and lasts a really long time - at least a year - before having to make another.

[@10sheds21]

I love these resourceful domestic recipes, I saw this on KZbin a few months ago as a way to make a silicone mould. The stuff has been sitting on my table since then now you have inspired me to give it a go. Thanks

[@andresart4902]

Here is a cool idea regarding 3D printers and this type of silicon-based material. I don't know the feasibility of this, but I would like to explore whether it would be possible. Here is a quick plan I've formulated on this subject: Adapting a 3D printer to work with materials like silicone and corn starch (similar to homemade Sugru) without using heat can be challenging. Standard 3D printers typically use a heated nozzle and extruder to melt and deposit plastic filament. However, using non-heated materials like silicone or corn starch in a 3D printer would require a significantly different setup. Here are some considerations and challenges: Material Properties: Silicone and corn starch have different physical properties compared to 3D printing filaments. They are not readily extrudable like plastic. They may require a specialized extrusion system. Extrusion Mechanism: A different extrusion mechanism, such as a screw or piston system, may be necessary to push these materials through the nozzle without heat. Viscosity: Silicone and corn starch-based materials can be viscous, which might require modifications to the printer's mechanics to handle the flow. Nozzle Design: You would need a custom nozzle designed for these materials, as the standard hot-end nozzle used for 3D printing plastic may not work effectively. Cooling and Solidification: Unlike heated plastic, silicone and corn starch would need time to cool and solidify. The printer would need to account for this in its design. Material Compatibility: Ensure that the chosen materials are compatible with the printer's components to avoid damage or clogs. Experimentation: Adapting a 3D printer for non-standard materials will likely require a lot of experimentation and testing to find the right settings and configurations. Safety: Make sure to consider safety precautions, especially when working with new materials and modifying the printer. In summary, while it's technically possible to adapt a 3D printer for non-heated extrusion with materials like silicone and corn starch, it would involve significant modifications and experimentation. You may also need to develop or modify the software to control the printer accurately with these materials. It's a complex undertaking that requires a good understanding of 3D printing technology and material science.

To clarify. Corn flour and corn starch are not the same thing. Corn starch is often called corn flour, but that is incorrect and they are two different things. Corn flour is made by grinding whole corn kernels. Corn starch is almost exclusively the starch from the kernel.

[@McRootbeer]

Does it change the properties of the oogoo? If not, no one cares

[@DB_000]

yes@@McRootbeer

[@McRootbeer]

@@DB_000 how?

[@AhoMcKee]

@@McRootbeer At least in the US, there is corn starch, a thickening agent, corn meal, which is flour you'd use to make cornbread, corn muffins, etc. Then there's masa flour which you'd use to make tortillas or nacho chips. You would only want to use corn starch here the others wouldn't work.

[@McRootbeer]

@@AhoMcKee you're the only one talking about masa and corn meal 😆. No one is confused.

[@alaingrignon]

@Rob I tried doing something similar when I needed to take a mold of the antiskid pattern from my boat deck to be able to stamp it into some thickened epoxy I was going to use to make a repair on deck. All I did was skirt a whole bunch of silicon in a bucket of soapy water, kneaded into a ball inside the bucket, then pressed it onto my boat deck and got the pattern out of it. let it set and had a block I could use to recreate the pattern. Weather all summer was terrible here so still have to make that repair.... but my plan was to put some thickened epoxy in the holes, let it set to tacky, then dab the mould into a bin of powdered sugar so it doesn't stick to the epoxy and stamp and repeat. once it sets, rise the sugar with water and presto... well at least that how it turns out in my head. :) Great video as always.

[@rfiskillingussoftly6568]

Or you could just glue a piece of rubber band to stop the noise! Easier to maintain a balanced product! Great video man!

[@JelMain]

No, talcum powder can have asbestos in it. The missing ingredient is naphtha, to thin the silicon.

[@DavidStarkdyvarg]

OMG! I've been working with silicone for years on several projects, just wishing for a solution exactly like this! Thanks a BILLIONDY, Rob!

[@kevinbowker2385]

Very cool, thank you for sharing!

[@preciousplasticph]

Corn starch works for filller too. The starch has some water in it so it will acclerate it. Recipe been on youtube for years. Even king of random did a video

[@zaleeu]

Wow, very helpful! Thanks~!

[@chuzzbot]

Great ep fella

[@ijcarroll]

The reason for corn starch vs talc is in the U.S. there's a discussion about talc causing cancer so corn starch is a safe alternative. I guess the uk isn't buying into the hype.

[@popepaul4438]

Thanks for this rob it will really come in handy

[@In_fluss]

Cool, thank you so much for the info. You are awesome. 😎😇🙏

[@PhilWaud]

Ive just come back to the channel Rob, your daily videos were getting a bit much to cope with, but the last couple Ive seen have been really interesting and this one is fantastic! Ive used sugru in the past, but its stupidly expensive as you say, and also you have to use a small amount at a time as once the pack is open the rest gets wasted. Thank you for this tip.

[@marcin4xm]

Ths is great ! Its exact contents im on this channel for .

[@AndreaDingbatt]

Robert, Thank you, yet Again!! I have Never seen Either of these before, but this is Exactly the kind of product, Ive been looking for,,,for one of my Art Projects!! Certainly I would Not be able to Afford the more Expensive Stuff~Because of the large Scale, Thus,,yet again, you have come to the Rescue,(**Especially of my Wallet!!) &, I Promise I will send you a Photograph of the finished Piece of Functunal Artwork, as soon as it Is finished!!

[@11Sam11]

Very nice.. This is exactly what Im after and your video came at the right time on how to make it yourself. Brilliant. Off topic: I thought I should mentioned if you place rubber tips along each bladed flaps where it folds and where the flaps meets as it closes will not only silence two plastics hitting together like a shock damper, but will also behave like shock spring absorber according to the rubbers spring constant. Therefore as each bladed flaps moves and hits in between where opposing rubbers are position. It will increase the rotors kinetic energy providing substantial amount of torque as it will bounce off away from each other in respect to its propelled swinging motion. Thank you as always

[@Bob.Jenkins]

I purchased seven Packets of Sugru and though they do work as advertised, I was more then a little unhappy to find that four of the seven packets had already hardened due to the poor packaging and I've never used the stuff again. Honestly, if I had the need I'd use the formula that you demonstrate here... a lot cheaper.

Hi Rob, Sorry to go off subject but I got excited after watching 1796 Building the Generator of the Future. I've looked for the bigger version but couldn't find it. Of all the generators you've discussed. Which one is the best. I want to integrate it with a Tesla Turbine.

I have been using commercial grade silicone that uses methanol as a crosslinking agent. It's still noxious, but not quite as bad.

[@baconpizza1239]

Permatex and others offer "sensor safe" silicone sealant that doesn't contain ascetic acid as the cure agent.

[@-COBRA]

basically every manufacturer offers acid free silicone

[@bobbybeaudoin]

just wondering for that particular project...will it not unbalance your whole wind turbine since you can't really put the same amount of Oogoo in each blade flap "receivers"?

[@AdricM]

i found it works just fine with corn starch. like 1 part corn starch to 10 parts silicone caulking works well. cures a little slower, but still under an hour or so.

[@lorenbush8876]

Don't they make rubberized 3D printing filament? That should be good for making rubber molds of things that would be destroyed by making a rubber mold that has to be vulcanized to cure it. Thanks Robert

[@chiperchap]

Wow Ive been looking to replace my silicone door seals but was looking at 60 quid for 2 doors. Was thinking of silicone and cling film and shut the door to make a fitted seal. The cleanup was putting me off but this could be the solution

[@McRootbeer]

Is there a way to store it for later use? Vacuum sealing in a bag or jar?

[@boobus72]

50% water and 50% dawn dishsoap + 100% silicone does the same without all of the powder.

[@whosle]

Thanks for sharing, the acetic acid smell can mess with your nostrils, so it is best cured in a well ventilated area. (It will remove your appetite for fish n chips if you overdo it!) Some folks have made a more flexible recipe using dish soap, but I have never been successful with that. Only downside to the cornstarch method is that the shore strength is pretty high, so it tears easily.

[@judyofthewoods]

I've not made any oogoo yet, but heard that you can adjust the amount of starch to get different amounts of hardness. Less starch, more elastic, but also longer curing time. More starch and you get something more like plastic. 50:50 is about firm rubber like.

[@quantumenergysolutions9128]

Cheers Mate! Any chance you can add your bio graphene to it?

[@glencahalin4786]

My thinking may be a little too simplistic but, if it gives of acetic acid while it cures wouldn't that then suggest acetic acid would also be a good "thinners" for it?

[@larcabout]

I've seen this on tkor, they call it proto putty

[@petevenuti7355]

If you added bicarbonate, maybe boric acid too and less starch wouldn't you get a bit of a lightweight foam that doesn't smell as much ?

[@timetravellingtoad]

How about using TPU filament for this purpose?

[@My2Drumsticks]

Seems incredibly heavy for your use. Won’t the generator have to be balanced to stop vibration?Why not super glue some sponge instead?

[@travismoore7849]

I wonder if that could be molded to make soles for shoes, But what could speed up water absorbing into the silicone other than a salt. And what powder would be good to mix for strength other an carbon or nano carbon.

[@mikegLXIVMM]

Thanks for posting this video. Sugru is too expensive

Will it behave like "Non-Newtonian fluid like" after drying? It's interesting !!

[@colleenforrest7936]

Talc had been shown to cause canser, may be why they went with corn starch. I've been playing with different flours to make s good Keto bread. Different flowers absorb moisture differently. I wonder how coconut flour would work? If you want to keep your rubber strips consistant, could you make a form for the ooGoo that would fit over the end of the blades and then line them with baking paper or maybe even a spritz of olive oil and let it cure in the form? Needs water to cure, so maybe after you form it, you can release the form anf if its the right condistancy it should hold its form... 🤔

[@j.f.christ8421]

Talc doesn't cause cancer. (It might, but the link is very tenuous.). What does cause cancer is that there was often asbestos in talc from how it's mined. Most (all?) talcum powder is now corn starch, oddly enough.

[@ile84]

Thats weird I've never heard of such "Sugru" stuff even. Well I suppose its different name here in Finland if it has landed here at all.

[@pvc988]

Will potato starch work? Corn starch is somewhat difficult to find in my area.

[@JelMain]

Yes, it's just a bulking agent to stop it behaving like bathroom sealant.

[@pvc988]

@@JelMain I am going to try tomorrow. EDIT: I tried and it's not sticking to the hands but curing time is about the same as for regular silicone.

[@judyofthewoods]

@@JelMain it has an additional function, to carry moisture into the depth of the material. Silicone alone would take a very long time to cure in any thickness as a cured film on the surface would slow moisture from the air penetrating into the material.
