Thermosil T7000 is a two-part, low-density silicone sealant used to create an abradable air seal for high-speed compressor blades in jet engines. T7000 meets Pratt & Whitney specification PWA 407 and is primarily used in operating environments with temperatures up to 525˚F (274˚C). Here are some more performance-proven features:
- High-compression glass microspheres and a proprietary microsphere surface treatment produce a securely cross-linked glass-polymer matrix that will not degrade during aggressive mixing or application, ensuring consistent hardness and durability throughout the product life cycle.
- High-instensity microsphere processing eliminates glass agglomerates that can clog turbine vane cooling holes and cause premature erosion and seal failure.
- T7000 offers outstanding adhesion during application. Cured material will not adhere to turbine blade tips.
- T7000 is low-viscosity and easily degassed for efficient application. It offers a working life of over 24 hours and is fully machinable when cured. Plus, its consistent black color provides a great looking finish.
Thermosil T7000 is available in a 2.74 kg A/B kit, or in pre-measured void-free component injection cartridges.
