## Description

FAQ: Q: How to elimiate all bubbles ? A: Bubbles tends to occur in high tempeature. You can seal and store the silicone in the refrigerator for 1 hour, then let it cure at room temperature. If you want to heat cure the silicone and shorten the curing time, make sure to degass the bubbles first. Q: Why silicone is sticky or non-cure ? A: Cure inhibition is one of the most common issues that can occur during the mold-making process. The platinum catalyst in the liquid silicone rubber can become deactivated by coming in contact with contaminants like UV RESIN,3D print resin, Sulfur-based clay, and Tin-cure silicone we suggest you read the manual carefully before the operation and always make a small patch test first.

### ⭐⭐⭐⭐⭐ Review
*by W***N on 19 December 2025*

This is great for a quick cheap mould! I had some small plastic interior trim missing in my classic car the parts are no longer available. so used this to make a quick mould and successfully cast what I need. The final result was a good copy and all the details were replicated. Its very easy to work with for beginners, this silicone is quite forgiving and flexible. The final mould isn't sticky and demoulds resin easily. do follow the instructions to de-gas the silicone as it reduces the bubbles.
