Thermosil 4000 is a thixotropic, two-part (A/B), silicone sealant that is applied as a potting compound for low-pressure compressor stator vanes in jet aircraft engines. Its superior elastic properties also allow it to function as a damping compound to minimize vane vibration and stress.
Thermosil 4000 meets the requirements of Pratt & Whitney specification PWA 404-2. It can withstand operating temperatures up to 350°F (177°C), and is available in pre-measured void-free A/B injection cartridges.
