Silicone Mold Making Kit, 30A Blue Platinum RTV-2 Liquid Silicone Rubber 9.8LB for Casting Resin, Soap, Candle, Clay, DIY Molds -1:1 by Volume with Tool 4 Cups,4 Sticks,2 Droppers,1 Pair Gloves

First time using this product and making silicon molds. Had to replicate a really rare decorative filigree, and this allowed me to make the mold very simply. Actually did not use it to create resin parts, but instead use the mold to fill with hot glue to be able to quickly make molded parts for my project. Will definitely order again if I have two mass produce parts from a silicon, self made mold.

Despite some of neg reviews I still decided to get this silicone. I never had a problem with it. I kept it at room temp...mixed for 3min then let sit for about a min. I made a sm holographic insert and a small holographic mold. I was able to demold at about 12hrs...still alittle sticky but within an 1hr or so it was fine and no bubbles ....will definitely buy again...

It works, but the 30A blue is a bit tough to work with. It takes way too long to set at room temperature if you're casting with alginate and want to pick up fine detail and texture. After thorough mixing, degassing, and pouring the silicone let it set for at least 72 hours at room temperature; demould carefully as it will prolly still be a little soft and tacky; flat side down if you can, bake at 200F for about a half hour to finish curing the silicone. Fully cured it should be about as hard as a contracted muscle. Alternately, just buy the 20A clear silicone of the same brand and follow the directions with no extra steps.

Tested product before use. Instead of 6-hour demold time it took more than 24 hours to cure, and even then the surface was sticky. Followed all instructions, and finally got it to set by putting it on top of my heating boiler for a day.

Ok..I have used the smaller bottles..and it work very good.. completely dry over night....and very pliable And I had gave it 5 stars...but...just so you know..the dry in 6 hours...not going to happen unless it's paper thin......so I did get the largest ones they make and I'm regretting it....I use what was lift of the older stuff on half of the mold..was dry next day...did the other side with the new...it's been 48 hours and not ready yet it has started to skim over...but probably going be sending it back...

This silicone was easy to work with and pour. No issues with bubbles or curing. It releases well and also conforms to molds well. The cured product seems to be very durable so far

This stuff sets up nice and slow to give plenty of time for air bubbles to escape and to capture fine details! Worked great for me.

The product worked just as advertised. I had no problems with bubbles and it turned out with a very smooth finish. The only regret I have is that I didn't buy more at their recent low sale price.
