IOTA 9120 is a liquid precursor polymer with repeating Si-N/Si-N-B units, functioning as both thermosetting resin and ceramic precursor. It pyrolyzes under mild conditions to form heat-resistant SiBCN ceramics. Curing via 120-180℃ thermal crosslinking or 80-100℃ Pt-catalyzed hydrosilylation (2-5h), it offers high ceramic yield and bonds metals/ceramics/graphite, suitable for CMCs, high-temp adhesives, and anti-corrosion coatings.

Key Performance Highlights

• Flexible Curing: Thermal curing in air/inert atmosphere or low-temp Pt-catalyzed curing, with 2-5h adjustable cycle.
• Controllable Ceramization: Amorphous SiBCN below 1600℃, crystalline above 1600℃; ceramic composition tunable via atmosphere (SiC+Si₃N₄ in N₂/Ar, Si₃N₄ in NH₃, SiBOCN in air).
• Multi-Substrate Compatibility: Low viscosity, dilutable with dry solvents, bonds to metals/ceramics/graphite (>2MPa), ideal for composite interface modification.

Application Solutions

• CMCs: Impregnates preforms for high-temp components (1500℃ flexural strength >400MPa), used in aerospace engines.
• High-Temp Adhesives: Bonds metal-ceramic with >70% shear strength retention at 1000℃, suitable for kiln assembly.
• Anti-Corrosion Coatings: Forms ceramic film resisting 1000℃ oxidation (weight loss <3%) and 1000h salt spray.
• Resin Modification: Enhances polymer heat resistance (HDT +60℃), enabling organic-inorganic hybrid materials.

Storage & Handling

Dilute with dry alkane/ether solvents; avoid water/alcohols/acids/bases. 1L/5L/20L sealed packaging, 6-month unopened shelf life, >2-month post-opening life under sealed low-temp storage.

IOTA 9120 empowers high-temp material innovation with dual-functionality and controllable ceramization,突破 traditional ceramic processing limits.
