Recently, an organic polyborosilazane (ceramicizable precursor polymer) called IOTA 9120 has attracted widespread attention in the materials field. It is expected to bring new changes to multiple industries with its unique performance and diverse application prospects.
IOTA 9120 is a liquid precursor polymer composed of repeated Si-N and Si-N-B units, which serves as both a thermosetting resin and a ceramic precursor. Under relatively mild conditions, it can decompose to produce SiBCN ceramic products with good temperature resistance, which makes it have great potential in high-temperature application scenarios.
The curing method of this material is very flexible. It can be crosslinked and cured in air or inert atmosphere at 120-180 ℃, and can also be cured through hydrosilylation reaction at 80-100 ℃ with the help of platinum catalyst. The curing time is generally 2-5 hours, which can be flexibly adjusted according to actual needs.
After high-temperature cracking, the cured material of IOTA 9120 will first transform into amorphous ceramics and eventually form crystalline ceramics. The composition of ceramic products is closely related to the cracking atmosphere and fillers, which provides more possibilities for the customized application of materials.
IOTA 9120 also has many excellent characteristics, such as low viscosity, short curing time, diverse curing methods, high ceramic yield, and good adhesion to materials such as metals, ceramics, and graphite, making it easy to prepare SiBCN ceramics.
It has a wide range of applications, including ceramic based composite materials, metal based composite materials, high temperature resistant adhesives, anti-corrosion coatings, high temperature resistant and anti-oxidation ceramic coatings, ceramic preform impregnates, thermosetting resins, and organic-inorganic hybrid materials. The emergence of IOTA 9120 undoubtedly injects new vitality into the development of materials science and deserves continuous attention from the industry.
