Using a platinum based translucent silicone rubber with a 1:1 mixing ratio opens up a world of possibilities for creators and professionals needing reliable, versatile moulds. Its easy use and strong mechanical properties make it a staple for detailed casting work.
Mixing and Preparing Your Silicone Rubber
This silicone rubber is designed for easy preparation, with a simple 1:1 ratio between base and catalyst. Measure both parts accurately by weight or volume, then blend thoroughly until the mix is fully uniform and streak-free. Take your time to ensure no unmixed material remains, as this can affect curing and mould performance. Once mixed, pour or apply the silicone promptly to your prepared model to take advantage of its working time.
Typical Applications and Benefits
The translucent nature of platinum based silicone rubber allows you to closely monitor material as it cures, which is particularly helpful for capturing fine details and undercuts in your moulds. This material is suitable for casting with epoxy, polyester, polyurethane, acrylic, plaster, cement and even hot wax, making it a highly adaptable choice for craftspeople, sculptors and candle makers alike. Its robust formulation offers strong resistance, low shrinkage, and a service life longer than many general-purpose silicones. A fast curing time—often between 3 and 8 hours—means your moulds are ready to use the same day.
Practical Tips for Best Results
- Carefully follow the 1:1 mixing ratio for optimal curing.
- Work in a clean, dry environment to prevent contamination.
- Degas the mixture if possible, especially for highly detailed objects, to avoid trapped air bubbles.
- Choose a mould container that can hold the silicone securely and prevent leakage.
- To further minimise shrinkage over time, cure the mould fully before use and avoid storing in conditions with extreme temperature changes.

When This Matters Most
This type of silicone rubber is most valuable when you require precise, reusable moulds for complex or highly detailed pieces across a range of casting materials. Whether producing prototypes, jewellery forms, or craft objects, its clear and consistent results can make all the difference.
