Long time listener. First time caller. Excited to be on your show guys. What I would like to do is make my own silicone bracelets / bands. Like Lance the liar Livestrong bands. But cooler. I've seen lots of posts on creating silicone molds. I think I can figure that part out. What I haven't found is a discussion on molding stretchy, rubbery silicone stuff. In my case - wrist bands. Anyone here have an idea on what to use and how/where to purchase? I chatted with the kids at Make Your Own Molds and they were helpful on making my mold. But they couldn't recommend a site to buy the silicone for the bands. Help!!

So I have created a negative of a sculpt (two part plaster) for a full head and top of shoulders mask; I would like to cast it out of silicone but I am not sure what to use... I need something available in uk that can stretch a lot (it is a tight mask so that it binds to your expressions) and is soft like skin. (And Cheap! :) tops around £30) I was thinking about platsil Gel 00 or 10. What do you think? Thanks! (And if you can, how much would I need?)

Hi all. I have an item that I need to make silicone copies of. I don't want silicone moulds, but the actual end product to be silicone. What is the best way to do this? I have tried looking up but everything is "silicone moulds for xxx" and not what I want. Thanks!

Does anyone have a silicone recipe that IS safe for food and can be put in the oven, safe up to 500 degrees? Or is there such a product already out on the market? I need it in liquid form, so I can make my own mold.

I am getting a silicone rubber skin/case for my Kindle in order to make a custom mount. In addition I need to put a compartment on the back of the case to house some electronics components. It will be put inside of a plastic enclosure, so I need to figure out how to secure that plastic enclosure to the back of the silicone case. I was thinking of using Velcro, but I don't know if that is secure enough, or if the adhesive backing is strong enough for either the plastic or silicone surfaces. What would be the best kind of adhesive in this situation?
Question by dmehling1 | last reply
I am looking to screen some patterns with silicone on different surfaces like hardboard, MDF, carboard etc. For that I diluted Silicone caulk with Xylene and added some normal oil paint. I was able to get positive result except that the dilution weakened the adhesion property of the silicone which ultimately failed the whole experiment. The screened layer was about 1mm thick. The cured layer could easily be removed by gentle rubbing with finger or thumb.

I was looking for a rectangle silicone mold to use for cold processed soap. I saw several that were called "soap mold liners". They were used to line or fit inside wooden soap molds. Right now if a soap maker uses a wooden mold, a lot of time is spent lining the mold with plastic wrap, or freezer paper......usually with less than stellar results. Silicone seems to be the answer. When I finally tracked down the silicone liners, I also found out that this company is no longer in business....... My DH made me a wonderful mold out of a large thick plastic (HDPE) cutting board, BUT while the soap doesn't leak out, or react to the plastic, it IS difficult to get the soap to "let go" of the plastic, so I end up lining it just to simplify the process. I would like to make my own liner from silicone IF I could get some direction form someone in the know. I have seen directions on the internet, but I think those are mainly ads to sell their product. My questions What silicone (brand) is best for a first timer? which release agent (brand)? could I use the actual HDPE soap mold as the outside of the mold without the silicone or release agent hurting it? can wood be used as the "mold" to create the cavity? Doe the wood have to be treated? where would I find these products Any other "suggestions" or advice? Thanks Mary

Burning question! I am trying to attach a membrame (which is made of latex at the moment) to a silicon housing (see attachment). The membrame should be a able to move vertically and thus expand a bit. The two challenges are: - The membrame should not be to thin, because otherwise it snaps and; - The membrame should not be to thick, because otherwise their is too much pressier on the sides and it also snaps. The membrame and the silicon housing should be airtied. The material of the membrame can change, although it needs to be flexible of course. Any tips on which material to use for the membrame or on assembly techniques? Cheers, Thijs

I want to reproduce a bit of jewellery I have designed in pewter by using a 2-part RTV silicone mould. By all accounts it is possible but I've run into some problems when sourcing materials. Most high temperature silicones I have come across state a maximum temperature of 250°C, But pewter has a melting point of around 280°C. My feeling is that the mould itself will most likely never actually reach 280°C and will probably only be above 250°C for a short period of time. But I'm wondering if anyone has actually done this and could verify for me. Also as I'm new to the whole process, any other tips are welcomed. This is the high temp silicone I'm currently looking at. Thanks, -Tom

I have tried everything I can think of get paint to adhere to silicone but will no luck. It peels off after a short time. If you know a solution to my problem, I will be very grateful.
Question by drifterdax | last reply
Plastic is easy, lots of stuff sticks to plastic, but the only thing that seems to stick to silicone is more silicone. Hot glue, super glue, Elmer's glue, Gorilla glue, and liquid steel epoxy all fail. Any suggestions? Maybe something marine related? (Background: I used some left over silicone molding compound to make a comfy handle, but it doesn't want to stay on.)

Hullo, just had a call from my mate who wants to do abit of pewter casting, now he had a very specific question about molds and the silicone to use, I had a look round but no one mentions a particular sort, I thought all silicone is silicone ... but decided to bring the question to the experts To make a silicone mold, for pewter casting, what sort of silicone should my friend use? He shall be making a belt buckle from what i gather. Thanks chaps Biggsy

I've tried other diy methods such as silicone caulk and Plaster to make molds. while the plaster was the closest to working it was very difficult to remove the resin from the mold.

Hello, I purchased a Polyurethane Resin mix (Part A/Part B) to create a guitar. I’m wondering though what material I can use to create the Mold? I normally work with Wood, so this is all new and exciting, but oh so confusing. Can I create a mold out of wood and coat it with a silicone spray? Do I need to use some other non-porous material? Any insight would be excellent. Thanks, Rich

Hi I'm trying to make a two part model in polyurethane resin with a thin silicone membrane connecting them so it can expend and still be maintained by the silicone layer. The problem is that i need to pour the silicone into the model, so i can't make them stick together with some coating or glue. Instead of the silicone i thought about using polyurethane elastomer but it is usually not very elastic and does not age well when frequently teared neither. So i'm searching for a way to pour silicone into polyurethan resin and make it stick. Maybe eventually by putting some fiber on the resin surface while wet so it'll get trapped in the silicone layer while it will catalyze but i doubt it'll resist to the tear strengh for a long term use. Did any of you tried it or found a solution to that problem ?
Question by naomori | last reply
Hi. I would really like to make some food-grade molds (candy molds). I know that food-grade silicone is the way to go, but here in Norway, it is not that easy to come by, and when you do, it's very expensive. My question is whether there are viable alternatives, that lasts. (not a make one, and break it thingy..) I know that aquarium silicone is supposed to be non-poisonous, but will it do as a mold material? Or are there other alternatives I can make myself? or buy at a hardware store.. I know there are a lot of silicone products out there.. Surely some of them would be safe to use in food prep? Thanks for all answers. Best regards, Klaus, Norway.

I am planning to cast jewellery by generally sand casting with wax models, though I would like to make more permanent silicone mold backups if something happens to the original wax master. My plan would be to pour or press silicone onto the wax master and get it out after the silicone has set. The only easy way I know of doing this is to cut a line all around the silicone mold to retrieve the wax master. I know other people seem to do this. I can't see how you could do this though without accidentally scratching the wax master inside?
Question by lsadwdwadw | last reply
I'm working on a portable high power LED system and I'm thinking of potting it in silicone for durability. It is gonna get banged around a lot... I need a little guidance. I've searched the internet and I can't figure out what silicone to buy? I'm looking for something as cheap as possible, but it needs to dry clear and feel somewhat like rubber when it is dry. Can someone help me find a CHEAP product online that will allow for this? Or maybe I should use epoxy? (would that come out really hard and plastic-like when it dries?) Also can someone point out the pros and cons of using this method? Will the epoxy increase the chances of the circuit overheating? Should I embed heat syncs against the mosfets and leds or what? An example of this occurring is in this instructable: https://www.instructables.com/id/Power-LED-s---simplest-light-with-constant-current/step9/permanant-ize-it/

For some small projects like a bicycle light housing, and selfmade handlebar-grips i am searching for the right material to use. i was thinking about using some kind of rubber-like material, probably silicone, so i can wrap it around the handlebar. unfortunately there are many different kinds of silicone to buy, all with different physical and mechanical properties - so i would like to know what silicone would be best for that project? or should i use something else? it should withstand moderate tearing while mounting, and should tolerate rain and sunshine, etc... thanks for your help!

Hey again,Does anyone have any experience with this Flexil hot melt rubber stuff I've seen about. It's a vinyl rubber that you melt in a pot around 170 degrees and then pour it over masters and formers to create moulds like you would with RTV silicone (except quite hot). The rubber can be remelted which is a benefit over silicone, but does anyone know of reasons why silicone is better for making moulds with (other than the master possibly melting).Link here: http://www.cfsnet.co.uk/acatalog/CFS_Catalogue__Flexil__554.htmlIncidentally, CFS is also a good place to buy pretty much all casting and moulding materials if you're in the UK at somewhat reasonable prices :-)

I'd like to make a custom fit computer keyboard protector, the type that's made to stay on while the keyboard is in use. This Ducky cover https://mechanicalkeyboards.com/shop/index.php?l=product_detail&p;=999 is very nice, but rare. Most keyboards have no properly fitting cover available. Also, it would be awesome to say 'I did that.' What material would be best, silicone? What mold material? Maybe I could cover the keyboard with plastic film and spray some silicone on top? It has to be really thin. I'm guessing pros would use a bottom mold, then squeeze a top mold own on it. Thanks.

Question by jenglish9 | last reply
Hi there, Does anyone have ideas on how to make/get hold of a silicon type material to make moulds of so called toe separators. Something which could be made to an individual's needs, i.e. I would make it for myself and if it works, to share it publicly, as I am sure those who suffer from having bunions would benefit extremely. Unfortunately the products available on the market most of the time don't work (and is waste of money and resources), as all of us have different toes, feet, alignments etc. Any ideas on how to make such material at home and cheaply are very welcome. THANK you in advance! To peace and comfy feet for all! P.S. I have attached a few photos of these products to give you an idea of what I mean. The silicone which is used is soft but sturdy enough, which doesn't hurt the joints of the toes. It would be great to be able to mould these around flip flops (and other shoes) permanently - so that they don't move about.

Ok, so I'm having some trouble finding solvents in quantities of under 5 gallons (5 is too much, and for this project 1 gallon is too) that arent acetone, MEK, or xylene (home depot and lowes carry those). Specifically I need Perchloroethylene because thats the solvent that E6000 glue is made with and is the glue I want to thin out. The datasheet indicates that 1,1,1-Trichloroethane, Cyclohexane, Methylene chloride, Chlorothane NU, Chevron solvent 1100, gasoline, Propyl acetate, or Toluene will also dissolve it, but I'd really like to stick with its manufactured solvent. I presume it would have some sort of pricey hazmat shipping charges or the necessity of some sort of licence and I would rather pick it up, so where (or who) can I order some from in the Detroit area?
