How to reduce the viscosity of Silicone caulk without weakening adhesion property? Answered

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.

Best adhesive for securing plastic enclosure to silicone surface?

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?

Does anyone make their own silicone molds? I have questions for you

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

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?

how could i bound polyurethane and silicone ?

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 ?

How to cut wax master out of silicone mold without damaging it?

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?

Need easy-to-find alternatives to food-grade silicone, to make molds. Would aquarium silicone do?? Answered

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.

Experience with the Flexil/Vinamold/Gelflex hot melt vinyl rubber?

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 :-)

silicone glue for potting my high power led system?

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?

Bunion separators made to suit an individual

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.

Sourcing solvents in michigan

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?

what kind of silicone (or similar) for non-slip mod to cases (or most anything)

Alright, I recently purchased a cheap silicone case for my new iPod, and it doesn't have the non-slip feature that the one on my old iPod (which got stolen) had. I really liked that, since it didn't slide around on the seat next to me while driving, so I could reach over and change the song without endangering myself and others. I was thinking of making an instructable on making any kind of case non-slip by adding a glue- or caulk-like silicone to the back of the case that can come in (or at least be modified to be ) any color. My plan is to give the old Tron-like lines to the case, to add non-slip functionality, but also to look cool (and cyberpunk). My question is, what kind of silicone (or like substance) would that be possible with? I'm assuming it would be able to last the life of the iPod, because a temporary mod (like perhaps one using creepy-crawlers mix or something of that sort would seem to be) would just not be practical.

Where can you get silicone gel that can be easily molded that does not degrade over time?

I need some kind of gel padding for an underlayment on a suit of non-ballistics body armor I am building. What I want is some kind of mixture I can mix up, dump in a shallow mold, let it cure, then pull it out and cut it to shape and put it in the suit. Preferably this gel would be pretty good at absorbing shock and would not degrade over time if kept in a sealed environment away from sunlight, like sealed in a plate in the suit.  Anyone know of anything like that that is easily available and not over priced? I noticed the silicone used to make molds for casting, would that work? My friend suggested ballistics gel but it seems like it would degrade over time.  Any suggestions would be greatly appreciated.
