This versatile silicone supports casting of various materials including plasters, concrete, wax, and low-melt metals, curing fully in 24 hours with negligible shrinkage.

## Description

SUITABLE FOR FOOD GRADE APPLICATIONS, SEE TB FOR POST-CURE REQUIREMENTS Smooth-On Platinum Silicones (platinum curative) cure at room temperature with negligible shrinkage. These silicones exhibit good chemical, abrasion and heat resistance. Materials such as plasters, concrete, wax, low-melt metal alloys or resins (urethane, epoxy or polyester) can then be cast into these silicone rubbers without a release agent. Smooth-Sil Platinum Silicones are used for rapid prototyping, wax casting (foundries and candle makers), architectural restoration and for casting concrete. READ the MSDS before using. See technical bulletin for usage instructions available at www.smooth-on.com. MIX RATIO: 100:10 by weight; POT LIFE: 30 mins; DEMOLD TIME: 24 hours; SHORE A: 40; COLOR: Pink

Review: Easy to mix and pour, makes great molds. - Mixed well, degased ok, had to vacuum it twice but made a really nice strong cast for my candle mold. It could be cheaper for the amount you get, but depending on your budget if it's worth it or not. The whole container made one 3" x 8inch candle mold, I use round shipping tubes to make my molds in.
Review: Endless Possibilities - Great product. Used it to make a pecan-shaped chocolate mold. Only downside was the cost - it took the whole box (nearly $50 for fairly close to 68 cubic inches of product, if anyone's interested) to make my one chocolate mold, but I plan to use it a lot and couldn't find one anywhere online. All-in-all, I was pleased with the outcome, as this was my first time ever working with a product like this. I do suggest, if you're a newbie like me, that you watch a few Smooth Sil 940 how-to videos to get tips before getting started.

### ⭐⭐⭐⭐⭐ Absolutely perfect
*by M***A on January 7, 2022*

Everything about this product is as stated in the description: no funny surprises, or bad ones. The product is extremely easy to use even for someone who never used silicone before (such as myself), as long as you follow the (extremely easy and concise) instructions your mold is gonna turn out great. I used it to create silicone molds for three dice sets that I can use to make chocolate dice for my D&D players, and they turned out amazing! It's a bit pricey for me, as I live in Europe and with taxes and stuff I ended up paying basically almost double the amount, but for something that is gonna last for sooooo long, it's a good investment. 10/10 would buy again!
