## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent
*by N***I on 21 November 2023*

It works pretty well

### ⭐⭐⭐⭐ Good material
*by A***R on 25 December 2024*

Useful for DIY but a bit costly, instructions for use and ease of using should be improved

### ⭐⭐⭐⭐ Wasn't easy
*by C***X on 20 February 2022*

The first pour did not set. I poured it all out the next day emptied the whole bottle of catalyst into it and mixed again slowly. This time it set well. Because of the viscosity of the silicone it takes a while to get a good even mix of the catalyst so don't repeat my mistakes. Mix slowly, making sure to reach the bottom and scrape the sides. Work in small batches. It's easier to make a 250 ml batch and get a clean pour then mix the next batch. The batches fuse seamlessly as long as your pour them same day. Not sure how humidity affects the curing of platinum silicone but i live in goa and it took me almost a day of drying to see all the silicone cure properly. Production mould shows good tensile strength and detail capture Will order next batch soon.
