Smooth-On Mold Star™ 16 Fast Platinum Silicone Rubber, Silicone Mold Making Kit - Pint Unit

Anything by smooth, Reynolds is an amazing product. Silicone mold, making material life, casting silicone or their platinum silicone for silicone mask making best products on the market hands-down

I make wax molds and the process of working with wax can be daunting. this product allows me to produce new wax parts for casting in a single day. the material is soft and rubber like. to get the best results I inject the wax with a 3d printed mold box.the silicone is not as sturdy as the high heat silicones by smooth-on but if you need parts fast this is the best option.

I had never used any silicone and never made any molds before. I chose this to experiment with because it looked simple. Turns out it was extremely easy to use. It didn't even need degassing, which was nice because I don't have a vacuum chamber.The only issue I had was that I wanted a food safe silicone. Even though the listing said it was food safe, the manufacturer says it is NOT food safe.

Have used this stuff for years, if you let the jar sit for too long on the shelf it will seperate and basically crystallize on the bottom. Just use a metal screwdriver or something like that to stir it up again scraping all the lumps and they will redisolve into the mix. If you don't it will effect cure times and hardness, as one would imagine, you need all the ingredients to make the mix work as designed.As someone else stated, they are not kidding about the 6 min pot life.Don't worry about timing the mixing of the 2 parts, just mix until the color is uniform and pour it.

This is a great, fairly easy-to-use two part silicone. I've made a couple of successful molds from it already! The bottles say to stir well before use, and my bottles have some solids on the bottom. When I bring up the stir stick it almost looks like crumbled, cured silicone, so I don't know if I need to stirVERY WELL, or just stir enough so the liquid is ready to be mixed?This is the QUICK CURE stuff. Be sure you have everything 100% ready to go before mixing, because when it says you have a 6 minute pot life, they MEAN IT. I had some mix left over from my first pour and thought "Oh well, lemme just do another really quick" NOPE, got about 3/4 of it poured into my second mold, and I would have had enough, BUT it was already thickening halfway through the pour, then it wouldn't flow anymore because it was on it's way to setting up.

Used to make my own molds and 1 year later and molds are still 100%.... Getting some more soon and its easy to use

This stuff is good dries fastI would say. This amount is good only for small castings for big casting ull need maybeLike 3 orders i was able to get. 2 moldsBoth mayb7” inches longBy 4” inches tallBy 2 widthExpensive but good so for small casting really goodI would buy this againMix Half and half of. Each containerMix it done pour. All set

This stuff works great and is very easy to use. I've actually purchased several sets of it. And had no problem making it work. I did have an issue with the package leaking, but I think that was Amazon's idiot driver who threw it over my back gate instead of walking to my front door. You do have to be quick since this is the fast setting, so be sure you have everything ready you want to pour on. It is messy to work with so put something down under it. Comes out a bright blue color.
