KDT Ceraset Polyureasilazane

Heat-and UV-Curable Ceramic Precursor   

KDT Ceraset Polyureasilazane ceramic precursor resin is a 100% "solids" liquid of low viscosity which rapidly solidifies upon heating to 180-200 °C. Thermal solidification can be achieved at lower temperatures with the addition of a free radical initiator such as dicumyl peroxide. Cure can also be effected at room temperature by exposure to UV radiation in the presence of a UV sensitizer. This resin is used primarily in ceramic-related applications such as ceramic matrix composites (CMCs), metal matrix composites (MMCs), ceramic MEMS, ceramic nanocomposites, and ceramic joining. Once solidified, the polymer can be heated to temperatures in excess of 1,000° C to convert it to silicon nitride and silicon carbide-containing ceramic materials.

KDT Ceraset Polyureasilazane is specifically designed for use in Ceramic Matrix Composites via Polymer Infiltration Pyrolysis routes (PIP), Ceramic Fiber, and other high performance ceramic applications where very high ceramic yield and processibility issues are important.

Suggested Applications:

• Ceramic Matrix Composites (CMCs)
• Metal Matrix Composites (MMCs)
