Premium Fast-Setting Platinum-Cure Silicone Rubber for Professional Applications
PlatSil FS-10 is a fast-curing, platinum-cured silicone rubber from Polytek Development Corp. with a Shore OO60/A13 hardness. With a pour time of 8 minutes and a demoulding time of just 25 minutes at 73°F, this 1A:1B system offers an exceptional combination of processing time and turnaround speed — ideal for production environments and rapid prototyping.
Key Benefits
- Fast-setting formula: 25-minute demoulding time at room temperature — further accelerated with Part X Accelerator or heat (max. 60°C).
- Long pour time relative to cure speed: 8-minute pour time provides ample time for mixing and pouring, even for larger volumes.
- Low viscosity: 4,200 cP for excellent detail reproduction and easy pouring without vacuum equipment.
- High tear strength: 157.9 pli (Die B) and 488 psi tensile strength for durable moulds in production series.
- Zero shrinkage: Platinum catalyst ensures dimensionally stable moulds without shrinkage or degradation over time.
- Excellent chemical resistance: Suitable for casting polyurethane, epoxy, polyester and foam without a release agent in most applications.
Typical Applications
- Rapid prototyping of flexible parts in product design and engineering
- Series mould making where fast turnaround is essential
- Casting of polyurethane plastic, foam and epoxy in production environments
- Brush-on blanket moulds for complex geometries (with PlatThix thickener)
- SFX and theatrical applications (not for skin contact) requiring fast demoulding
- Industrial applications in automotive, architecture and consumer products
Technical Characteristics
PlatSil FS-10 is mixed in a 1A:1B ratio by weight. Pour time: 8 minutes. Demoulding time: 25 minutes at 73°F (can be accelerated with Part X or heat). Shore hardness: OO60/A13. Viscosity: 4,200 cP.
