Clariant enhances technology platform for functional coatings and composites by acquiring KiON
Polysilazanes are silicon-containing polymers that can be used to produce coatings on a wide variety of substrates. These coatings, being only a few micrometers thick, have excellent adhesive properties, making them ideal for various protective functions. Polysilazanes are also precursors to silicon carbide and silicon nitride ceramics. In addition to ceramic coatings, these preceramic polymers are used to produce both ceramic fibers and the matrices for three-dimensional ceramic matrix composites (CMCs). Such ceramic composites, which are lightweight and combine high strength and toughness with exceptional high temperature durability, are suitable for applications in which other materials do not perform. Some applications, for instance, include components used in aircraft, turbine engines, microelectronics, and in highly corrosive environments.
