IOTA 9120 is an innovative liquid precursor polymer structured with repeating Si-N and Si-N-B units, serving dual roles as a thermosetting resin and ceramic precursor. It converts to high-temperature-resistant SiBCN ceramics under mild pyrolysis: amorphous below 1600°C, crystalline above 1600°C, with ceramic yields exceeding 50% at 800°C and density of 1.70-2.00 g/cm³. Pyrolysis atmosphere tailors ceramic composition—SiC/Si₃N₄ (N₂/Ar), Si₃N₄ (NH₃), or SiBOCN (air)—making it ideal for extreme heat applications.

Versatile curing options meet industrial needs: crosslinking at 120-180°C (air/inert atmosphere) or hydrosilylation at 80-100°C with platinum catalyst, ensuring 2-5 hour curing cycles. With viscosity of 10000-20000 cp (dilutable with dry solvents) and excellent adhesion to metals, ceramics, and graphite, it excels in ceramic matrix composites (CMCs), metal matrix composites, high-temperature adhesives, and anti-oxidation coatings.

Boasting 99.9% solid content and near-zero VOCs, it aligns with eco-friendly manufacturing. Packaged in 0.5-20L sealed plastic drums, it offers a 6-month unopened shelf life and >2-month usability post-opening under sealed, low-temperature, dry conditions. Avoid water, alcohols, and acids/bases; clean tools with acetone or solvent oil promptly.

From aerospace heat-resistant components to precision electronics coatings, IOTA 9120 delivers fast curing, high ceramic conversion, and extreme temperature resistance. Choose IOTA 9120 to elevate your high-temperature material performance.
