IOTA-9120 is a liquid precursor polymer composed of repeating Si-N units and Si-N-B units. It functions both as a thermosetting resin and a ceramic precursor, capable of converting into high-temperature-resistant SiBCN ceramic products through pyrolysis under relatively mild conditions. It is an ideal choice for ceramic matrix composites, high-temperature adhesives, oxidation-resistant coatings, and more.
Low Viscosity: Excellent flowability, facilitating impregnation, infiltration, and coating processes.
Short Curing Time: Improves production efficiency, suitable for industrial applications.
Multiple Curing Methods: Can be thermally cured (120–180°C, air or inert atmosphere) or cured via hydrosilylation reaction using a platinum catalyst (80–100°C, 2–5 hours).
High Ceramic Yield: >50% ceramic yield at 800°C; pyrolyzed ceramics are dense (density 1.70–2.00 g/cm³).
Excellent Adhesion: Bonds well to metals, ceramics, graphite, and other materials.
Easy Preparation of SiBCN Ceramics: Pyrolysis under nitrogen or argon yields SiC + Si₃N₄; under ammonia yields mainly Si₃N₄; under air yields SiBOCN.

Pyrolysis atmosphere affects final ceramic composition:
Nitrogen/Argon → SiC + Si₃N₄
Ammonia → Mainly Si₃N₄
Air → SiBOCN
Fillers can also affect the pyrolysis process of the cured product and the final ceramic composition.
