Amazing Mold Rubber
This tin-cure silicone is made for clean, accurate mould making with very little fuss. The low-viscosity mix pours smoothly and settles into fine textures without needing a vacuum chamber which keeps setup simple. It cures quickly, holding onto detail well and giving you a mould that stays flexible but strong enough to deal with repeated demolding. It suits both straightforward one-piece moulds and more complex multi-part layouts where undercuts or deeper shapes need a bit more give.
Because it is durable and resistant to tearing, it holds up nicely over multiple casting cycles. It works with a range of materials including resin, wax, soap and even chocolate which makes it a solid choice for both hobby crafting and small creative projects. The finish releases cleanly without leaving sticky residue which helps preserve the detail and keeps the mould looking tidy for the next round.
- Fast-curing tin-cure silicone
- Low viscosity for easy mixing and pouring
- No degassing required
- Captures fine details and textures
- Flexible and long-lasting
- Excellent tear resistance
- Suitable for resin, wax, soap, chocolate and more
- Clean release with no sticky residue
For the best results, mix steadily, pour in a thin stream and let the silicone settle so it fills every contour before curing.
