As temperature resistance demands in aerospace, defense, and high-temperature industries continue to rise, conventional organic resins can no longer meet extreme service conditions. IOTA 9108 Organic Polysilazane (also known as a ceramifiable precursor polymer) — with its low viscosity, high ceramic yield, excellent adhesion, and ability to withstand 1500°C — has become an ideal choice for Ceramic Matrix Composites (CMCs), Metal Matrix Composites (MMCs), and high-temperature adhesives.
High Ceramic Yield: >55% ceramic yield at 800°C; >75% from cured product at 800°C
Temperature Resistance Beyond 1500°C: Ceramified product withstands long-term service at 1500°C
Low Viscosity (10–30 cp): Excellent flowability — easy impregnation of fibers, fabrics, and porous preforms
Multiple Curing Methods: Thermal, photo, or moisture curing — flexible processing
Excellent Adhesion: Strong bonding to metals, ceramics, graphite, and other materials
Adjustable Ceramified Density: 1.60–2.00 g/cm³ — meets different performance requirements
| Application Area | Specific Use | Core Value |
|---|---|---|
| Ceramic Matrix Composites (CMCs) | Precursor impregnant for fiber-reinforced SiCN ceramic matrices | Mild pyrolysis conditions reduce fiber damage; high densification efficiency |
| Metal Matrix Composites (MMCs) | Interfacial layer or matrix modification | Improves high-temperature oxidation and corrosion resistance of metal matrix |
| High-Temperature Adhesives | Bonding ceramic, metal, and graphite components | Stable bonding at 1500°C — suitable for aerospace thermal structures, missile components |
| Ceramic Preform Impregnation | Densification treatment of porous ceramic green bodies | Increases density and strength; reduces sintering shrinkage |
| Parameter | Value |
|---|---|
| Appearance | Colorless to light yellow liquid |
| Solid Content | >99% |
| Molecular Weight (Mn) | 700–900 |
| Viscosity | 10–30 cp |
| Ceramic Yield (800°C) | >55% |

| Ceramified Density | 1.60–2.00 g/cm³ |
IOTA 9108 enables the production of Ceramic Matrix Composites without requiring repeated high-temperature sintering. Using the precursor infiltration and pyrolysis (PIP) process, it produces a 1500°C-resistant SiCN ceramic matrix under relatively mild conditions, significantly reducing manufacturing costs and process complexity.
