Easy to use, great working time and strong upon curing. It's also well worth mentioning that the level of detail you can capture with this product is mind blowing. Work as advertised, and intended which is ideally what you want for any product at the end of the day.

The product is easy to mix (use a scale), the mix of colors tells you when ready to use, it is tick enough to hold itself but will fit the tiniest crack, will cure in 4-6 hours (I added an infrared heater to help), will detach easily and remain flexible, solid and firm after curing. I use it to duplicate concrete wall stones and it works very well. NB: Make sure your structure has no leak otherwise the liquid rubber will seek through.

⭐️⭐️⭐️⭐️⭐️ Excellent Quality Silicone for Molds!. Silicone is fantastic! It’s easy to mix and pour, and it captures every fine detail perfectly. The curing time is very reasonable, and once set, the mold is strong, flexible, and durable — perfect for resin, clay work. releases cleanly, making the whole process so much easier. This silicone gives professional-quality results every time. I’ll definitely keep using it for all my future projects!

This stuff is the best! I'm molding small resin pieces for jewelry and displays, and using the Crystal Clear resin in the molds. I realized after two molds, that my cure time was longer because my house was a little cold. But really. It ended up with no air bubbles in it even!! I'm in love.
