IOTA 9108 is a liquid polysilazane with repeating Si-N units, dual-functional as thermosetting resin and ceramic precursor. It converts to SiCN ceramic resistant to 1500℃ via pyrolysis under mild conditions, offering a revolutionary solution for high-temperature material preparation. With low viscosity (<500 mPa·s at 25℃), it enables versatile processing (impregnation, spraying, brushing) and bonds strongly to metals, ceramics, graphite (>2.0MPa adhesion),adhesion challenges of traditional high-temperature materials.

Key Performance Advantages

• Flexible & Efficient Curing: Supports thermal (120-180℃), UV curing, etc., with short curing time (2-5h). Thermal crosslinkers further reduce temperature and cycle time, boosting productivity.
• High Ceramic Yield & Temperature Resistance: 85% ceramic yield, forming dense SiCN structure stable at 1500℃ with excellent oxidation resistance (<3% weight loss at 1000℃ in air).
• Multi-Substrate Compatibility: 0-class adhesion (cross-cut test) on metals, ceramics, graphite, enhancing composite interlaminar strength by >30% as interface modifier.

Versatile Application Scenarios

• Ceramic Matrix Composites (CMCs): Impregnates preforms to fabricate aerospace engine combustors, turbine blades with flexural strength 450MPa and fracture toughness 3.5MPa·m¹/².
• High-Temperature Adhesives: Bonds metal-ceramic joints with >80% shear strength retention at 1200℃, suitable for high-temperature furnace assembly.
• Anti-Corrosion Coatings: 10-50μm ceramic coating resists 1000h salt spray and 5000h QUV aging, protecting metals from high-temperature corrosion.
• Resin Modification: Blends with epoxy/silicone resins to increase HDT by >50℃, expanding thermoset applications in high-end fields.

Usage & Storage

Dilutable with alkane/ether solvents; avoid water, alcohols, acids/bases. Packaged in 1L/5L/20L sealed drums, 6-month unopened shelf life, >2-month post-opening life under 0-5℃ storage.
