CRAFT RESIN 模具製作矽膠 30A 8.8磅 | 液態橡膠模具材料

Used this to make a mold of a small statue and the detail transfer was spotless, even the tiny grooves came out crisp. The firmness of the 30A meant I could demold early without any warping, and it held its shape perfectly through three castings so far.

I was nervous about air bubbles ruining my first mold, but this platinum-cured silicone poured so smoothly that I didn't need a vacuum chamber. The 30A firmness held every tiny detail of my prototype across three casts without any tearing, which surprised me for an 8.8lb batch.

The firm 30A shore hardness is exactly what I needed for detailed coasters—the edges stay crisp even after the tenth pour. It's easy to mix and degasses quickly, so I didn't have to babysit it for long.
