Pure Sil 30 Silicone Rubber – 1.03kg
Pure Sil 30 Silicone Rubber is a two-part, tin-catalysed, condensation-curing silicone designed for durable mold-making. It cures with excellent tear resistance and low shrinkage.
Because it has a Shore A hardness of 30, it’s firmer than Pure Sil 20 and ideal for long-lasting molds. Moreover, it captures fine textures and sharp edges with precision.
Mix Part A and Part B at a 100:3 ratio by weight. Stir thoroughly and pour in a steady stream to reduce bubbles.
Use Pure Sil 30 in:
- Resin, wax, and gypsum mold-making
- Prototyping and texture replication
- Educational kits on polymer chemistry
Additionally, it works with epoxy, polyester, and urethane resins. You can also cast low-melt alloys and gypsum-based polymers.
Although it’s not food-safe, it suits economical mold-making for art, craft, and industrial applications.
For brush-on molds, add RTV Thixo thickener. To speed up curing, use Pure Sil Accelerator.
Ultimately, Pure Sil 30 offers strength, detail, and reliability—perfect for artists, educators, and makers seeking professional results.
