In high-end sectors such as aerospace, energy, and advanced manufacturing, extreme temperatures and complex chemical environments pose unprecedented challenges to materials. Traditional coatings and structural materials struggle to maintain stability under prolonged high temperatures, corrosion, and thermal shock. Today, we proudly introduce Polysilazane IOTA 9120—a ceramic-precursor polymer that combines the processing convenience of a thermosetting resin with the high-temperature resistance of advanced ceramics, opening new pathways for high-temperature protection and composite material fabrication.

Why Choose IOTA 9120?

1. Dual Functionality, One Material with Multiple Capabilities
IOTA 9120 serves both as a high-performance thermosetting resin, capable of cross-linking and curing at 120–180°C, and as a precursor for high-temperature-resistant SiBCN ceramics through pyrolysis under mild conditions. Its flexible curing mechanisms support thermal curing in air or inert atmospheres, as well as hydrosilylation curing at 80–100°C with the addition of a platinum catalyst, achieving curing in just 2–5 hours—significantly reducing energy consumption and process complexity.

2. Tunable Ceramization for “Material Design Freedom”
During high-temperature pyrolysis, IOTA 9120 transforms into an amorphous ceramic, gradually crystallizing above 1600°C. More importantly, its final ceramic composition can be precisely controlled by the pyrolysis atmosphere:

• Nitrogen/Argon → Forms SiC and Si₃N₄ composite ceramics

• Ammonia → Primarily produces high-purity Si₃N₄ ceramics

• Air → Generates SiBOCN multi-component ceramics

Combined with functional fillers, users can further optimize the microstructure and properties of the ceramic product, truly achieving “customizable ceramics” on demand.

3. Excellent Processing Performance and Substrate Compatibility
With low viscosity and high ceramic yield, IOTA 9120 is easy to process via impregnation, spraying, injection molding, and other methods. It exhibits excellent adhesion to metals, ceramics, graphite, and other materials, making it suitable for ceramic matrix composites, high-temperature protective coatings, and high-temperature structural components.

4. Convenient Use and Stable Supply
The product can be diluted and formulated using dry solvents but must be protected from water, alcohols, and protic substances. It is available through stable large-scale supply with reliable quality, providing a solid foundation for industrial applications.

Whether you are developing coatings for next-generation aero-engine hot-section components, corrosion-resistant linings for high-temperature chemical equipment, or advanced high-temperature composites, IOTA 9120 offers tunable performance, flexible processing, and dependable solutions.

Choosing IOTA 9120 is not just selecting a material—it is embracing a future-oriented material design philosophy and technological pathway.
