How To Make Your Own Sugru Substitute

Step 2: Materials

Materials to Make Oogoo:

100% clear silicone caulk-the kind that gives off the vinegar smell while it cures. Can be found in any hardware store or Walmart. It cost from $3 to $5 for a 10 oz. tube. The newer silicone caulks that have a different smell such as GE silicone II will not work for this.

Caulking gun for silicone tubes.

Mixing cups

Popsicle sticks

Gorilla instant glue

Gorilla tape

100% Corn Starch

Linseed based oil paints to color oogoo


Materials to embed an etched circuit:

Clear Contact vinyl shelf liner from Walmart or hardware store.

Ferric Chloride etchant

Gorilla white glue

Surface mount LEDs

Magnet wire or conductive thread

Veil shield conductive cloth from http://www.lessemf.com/

can you make it with out 100% corn starch?

[edo4]

Has anyone tried using powdered tempera paints for coloring? Curious to know if that works or not.

[DMasters]

You mention GE silicon II doesn't work due to it being neutral-cure. I was curious if you think there's an alternate method which would allow neutral-cure caulk to be used for the same purpose. I ask mainly because GE silicon II K/B supreme is what I have handy, and would rather be able to play around with my leftovers before buying a fresh tube of (hard to find around here) acid-cure.

[DMasters]

Update: GE Silicone II K/B Supreme is a neutral alkoxy moisture curing caulk. The process, for the purposes of this 'ible, is the same as for the acetoxy moisture cure you get with the acid-cure caulk used here. The only downside is that it would be harder to tell when it's done curing because the vinegar smell isn't there.
(Tried it anyway; it reacted identically to the acid-cure Silicone I, and set up just as well. Obviously, still waiting on full cure.)

[Brad I.]

Was wondering what the end result of your silicone II curing experiment was? Did it set well? Thanks

[DMasters]

Just to see the difference, I made the same model with both the silicone II and an acid cure silicone caulk with a 3 to 2 ratio of caulk to corn starch. The acid cure sets quite firmly, while the neutral cure still has a little give and flexibility even after full cure. In the end, the difference is minor, as long as it's a moisture-curing caulk.

[bstullis]

any ideas on how to make the silicone II more rigid (didn't use any gorilla glue in my initial experiments), does the gorilla glue make the structure stronger or just make it stick like sugru to just about anything?

[apocalipstick]

Anyone in Sweden or in the nordic countries who knows what the ingredients might be named here? especially the glue. and type of silicone?

[Tiktaky]

There are two glues listed on this page, Gorilla instant glue which is a Cyanoacrylate glue usually called "super glue". It is a thin clear liquid that goes tacky in a few seconds and dries fully within minutes leaving a resin.

The second glue mentioned Gorilla white glue is Polyvinyl acetate, or PVA glue, sometimes known as Craft Glue or White Wood glue.

Corn Starch is sometimes known as Corn flour, It's commonly used to thicken gravy and custard.

Gorilla Tape is also known as Gaffer tape, cotton Cloth Tape or synthetic duct tape,

The Silicone is a tricky one because mikey77 doesn't mention any brands, So I'm not sure which he is on about. mikey77 says you want one with a vinegar smell which excludes Acylic or latex silicone caulking.

By that logic you want 100% silicone caulk, I'm not sure what brands are available in Nordic Countries, But if you go to a hardware store and find someone who is familiar with their stock you should be able to find a brand that does not add other polymers to the caulk.

[blerpherp]

Will F 109 Silicone work?? (Dimethyl siloxane, hydroxy terminated, silica amorphous, methyltriacetoxysilane, Ethyltriacetoxsilane, and other bunch of stuff on the label) the label states the caulk as 100% silicone...

[Scoop35]

Will Acrylic and Latex Caulk with Silicone work?

[gtoal]

Not if it is Type II silicone, which it probably is.

CLEANING and SMOOTHING -useful tip

I have found that a hand Grease remover (sold as Swarfega in the UK) get the stuff off your hands, if you don't wait too long. After rubbing it into my hands I tried smoothing my oogroo work and, yes, it works very well producing a nice shiny smooth finish. Two birds with one stone.

[icreatestuff]

can i use regular duct tape instead of gorilla tape?

[bobbubbles]

er... how do i get these things??
i live in australia! :(

[cunningfellow]

You can get these things in Oz....

Silastic is the silicone - also available as a variety of other brands
Cornstarch is called 'cornflour' in Australia.... but laundry starch powder is essentially the same stuff, and cheaper.
Gorilla instant glue is SuperGlue (cyanoacrylate glue)
Gorilla white glue is the same as Aquadhere in Australia (any white PVA glue)
Ferric Chloride etchant - go to Alltronics or Dick Smith or Tandy - they sell it as a solid you dissolve, or a liquid.

Hope this helps!!

[Loserima]

err... do you have google in australia if so type the materials into the search bar 1 at a time possibly accompanied by the word buy or purchase click on the links and magic where to buy the materials

[bobbubbles]

u dont hav to ask, google is EVERYWHERE!! o.O
thanks for the suggestion, ill look into it...

[SteampunkManiac]

Scary, if you think about it.:-)

[Loserima]

except for china but yea and probly some other countries ruled by communism but nyways noprob also check your local hardware store and any craft store, the corn starch will probly b at your supermarket tho

[bobbubbles]

actually, google is in china...
i saw a pic of a google centre with chinese people there and the caption said something about celebrating how china had google...

[cunningfellow]

I'm currently in China, and unless you use a VPN (proxy server outside China) the Google results are heavily censored, and many Google features (blogs, profiles etc.) just don't work.

[uberdum05]

They've censored google in China?!

[greintsma]

where have you been? Of course It's censoredas well as YouTube and the rest of the internet and other media.

[uberdum05]

I didn't know about it when I posted the comment at that time, now I do after it gaining so much news coverage and various things with Google trying to negotiate with the chinese government to get some services uncensored

[bobbubbles]

what bout you? its been a year

[Ragnarocker]

Oogoo is fantastic, thank you. This is truly 'Power to the People".

[mastroprimo]

My simply ask is : use bicarbonate powder like the modelist maker use this with cianolacrilate clue to fill tha gap in the models?
Tank yuo.
N.

[cacorro]

will this work with latex based caulk? it's way cheaper than silicone

[shaune23]

If it is much cheaper then give it a try and tell us about your results.

[Whales]

Ugh, poor me. Im broke and dont hae any silicon glu/gel around. Otehr wise i would have something to do.

[Peantoo]

A tube of silicone sealant costs about $2 at wal-mart. The gorilla glue is the pricey stuff!

[cscottbsn]

Check harbor freight tools if you have one nearby...i spotted some on the shelf and we know they are cheap :o)

Hey, would talc (magnesium silicate, aka baby powder) be a better choice than corn starch? Corn starch is food and therefore more likely to attract things that want to eat it (bugs, rodents, bacteria...), whereas talc is a mineral and generally non-reactive.

Any thoughts or experiments in this regard?

[scubapol]

Yesterday I tried a mix of talc with silicone. It was almost 2 parts talc and 1 part silicone. The mix was a lot easier to steer compared to 1 to 1 cornflour - silicone mix. The resulting Oogoo was more solid and took less time to cure.

[Replicator]

Most talcum powders these days are made from corn starch.... Apparently genuine talcum powder isn't very good for you?

[MadScientistK]

Correct! Baby powder and most other body powder now contain cornstarch rather than silicosis-inducing talc, so check the labels if you actually want talc. And use your particulate filtering mask while you're mixing.

[crazycloud]

Also great instructable!

[crazycloud]

Talc is def. bad. Never use it in vaginal areas if you have the old real talc around as it causes cervical cancer.

[1stage]

Good to know. http://en.wikipedia.org/wiki/Talc#Safety proves your point...
