## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to use, great results
*by J***R on February 5, 2025*

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.

### ⭐⭐⭐⭐⭐ A funcional silicone
*by T***D on January 25, 2025*

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

### ⭐⭐⭐⭐ Works OK, But Needs a Few Extra Steps
*by B***D on June 3, 2025*

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.
