High-performance organic polysilazane IOTA 9108: ushering in a new era of high-temperature-resistant ceramic materials

In the field of advanced materials, the organic polysilazane IOTA 9108 is attracting industry attention with its innovative approach. As a representative of ceramic precursor polymers, this product, through its unique molecular structure, bridges the gap between organic and inorganic materials, providing a brand-new solution for applications in extreme high-temperature environments.

The core advantage of IOTA 9108 lies in its "dual identity": it is both a low-viscosity liquid resin and a material that can be converted into high-performance ceramics through pyrolysis. Its key technical highlights include rapid curing, supporting both thermal curing (80°C-280°C) and UV curing (365 nm), allowing crosslinking to be completed in as little as 20 minutes, significantly improving production efficiency. It offers extreme temperature resistance, as the SiCN ceramic formed after pyrolysis can withstand temperatures up to 1500°C while maintaining oxidation and corrosion resistance, making it suitable for high-temperature industrial applications. Additionally, it achieves highly efficient ceramic conversion, with a ceramic yield exceeding 75% at 800°C and crystallizing into high-performance ceramic phases such as SiC and Si₃N₄ above 1400°C, offering excellent microstructural control.

Thanks to its outstanding adhesion to metals, ceramics, graphite, and other substrates, IOTA 9108 has been applied in multiple industries. In advanced manufacturing, it serves as a precursor for ceramic matrix composites (CMCs), aiding the development of high-temperature components for aircraft engines and thermal protection layers for hypersonic vehicles. In industrial protection, it is used to manufacture high-temperature-resistant adhesives and anti-oxidation coatings, safeguarding industrial furnaces and petrochemical cracking equipment from heat and corrosion. In electronic packaging, its organic-inorganic hybrid technology enhances the stability of electronic components in high heat flux density environments.

This product is based on polysilazane (Si-N repeating units) and achieves high process flexibility by precisely controlling its molecular weight (700-900 Mn) and solid content (>99%). It can be applied directly without solvents and is compatible with specific crosslinking agents (such as DHBP) or photoinitiators (such as 1173), making it suitable for various processing techniques such as spray coating and impregnation. Furthermore, its structure can be precisely controlled, as the ceramic phase of the final product can be adjusted by modifying the pyrolysis atmosphere (nitrogen/ammonia/air), enabling the production of both amorphous and crystalline ceramics.

Compared with traditional ceramic forming technologies, the liquid precursor characteristics of IOTA 9108 significantly reduce processing and manufacturing costs. It offers high forming flexibility, allowing the production of complex-shaped ceramic components, thereby reducing machining waste. Additionally, its low-temperature curing and rapid crosslinking properties lower energy consumption, aligning with carbon neutrality trends.

The introduction of IOTA 9108 marks a critical turning point in transitioning ceramic precursor technology from laboratory research to large-scale industrial applications. This product has already obtained multiple international certifications and is widely used in the aerospace, renewable energy, and semiconductor industries. As pyrolysis processes and formulation systems continue to be optimized, IOTA 9108 is expected to drive the development of ceramic matrix composites toward wider temperature ranges and more complex working environments, injecting new momentum into global high-end manufacturing.
