Product Overview
IOTA 9120 organoborosilazane is an innovative liquid precursor polymer with a core structure of repeating Si-N and Si-N-B units. It dual-functions as both a thermosetting resin and a ceramic precursor, enabling the synthesis of high-temperature-resistant SiBCN ceramics via mild pyrolysis. With low viscosity, versatile curing methods, and high ceramic yield, it stands as the ideal material for aerospace, electronics, and new energy applications.
Key Advantages
-
Dual-Functional Versatility：Acts as a thermosetting resin for direct use or converts to SiBCN ceramics via pyrolysis, adapting to both ambient-temperature processing and extreme-environment applications.
-
Efficient, Controllable Curing：Supports cross-linking at 120-180℃ (air/inert atmosphere) or Pt-catalyzed hydrosilylation at 80-100℃, with curing times of 2-5 hours, suitable for large-scale production.
-
Extreme Environment Endurance：Pyrolyzed cured products form amorphous ceramics below 1600℃ and crystalline ceramics above 1600℃. Generates SiC/Si3N4 under N2/Ar, SiBOCN in air, delivering exceptional heat resistance, oxidation resistance, and ablation resistance.
-
High Compatibility & Stability：Strong adhesion to metals, ceramics, and graphite; 99.9% solid content ensures low volatility and odorless operation. Dilutable with dry solvents for easy coating/impregnation of complex components.
