A new organic polysilazane precursor polymer, IOTA 9120, has recently been launched, offering dual functionality as both a thermosetting resin and a ceramic precursor. This innovative material enables efficient cross-linking at moderate temperatures and converts into high-performance SiBCN ceramics upon pyrolysis.

IOTA 9120 can be cured at temperatures between 120°C and 180°C under either air or inert atmospheres. Alternatively, with platinum catalyst, it cures rapidly at 80–100°C, offering flexible processing options. Its cured products exhibit a ceramic yield of over 50% at 800°C, forming amorphous ceramics below 1600°C and crystalline ceramics above that temperature, depending on the atmosphere used.

With low viscosity, high ceramic yield, and excellent adhesion to metals, ceramics, and graphite, IOTA 9120 is ideal for use in ceramic matrix composites (CMCs), metal matrix composites, high-temperature adhesives, protective coatings, and anti-oxidation ceramic layers. The product is moisture- and alcohol-sensitive and must be stored under dry conditions. Unopened containers have a shelf life of up to six months.

As demand for high-temperature materials grows in aerospace and advanced manufacturing, IOTA 9120 is set to play a key role in advancing next-generation ceramic technologies.
