Recently, the organic polyborosilazane (ceramizable precursor polymer) IOTA 9120 developed by Anhui Aiyuotta Silicone Oil Co., Ltd. has attracted wide attention in the materials industry. With its unique properties and broad application prospects, this new material is expected to bring about changes in multiple fields.

IOTA 9120 is a liquid precursor polymer composed of repeating Si - N units and Si - N - B units. It has a "dual identity", as it can be used both as a thermosetting resin and as a ceramic precursor. Under relatively mild conditions, it can be pyrolyzed to form SiBCN ceramic products with good temperature resistance, which gives it great potential for applications in high - temperature environments.

This material has a variety of curing methods. It can achieve cross - linking curing in air or an inert atmosphere at 120 - 180°C, and can also complete curing through a hydrosilylation reaction at 80 - 100°C with the help of a platinum catalyst. The curing time usually only takes 2 - 5 hours. After high - temperature pyrolysis, the cured IOTA 9120 will first transform into an amorphous ceramic and finally form a crystalline ceramic. The composition of the ceramic product is closely related to the pyrolysis atmosphere and fillers.

IOTA 9120 also has many excellent properties, such as low viscosity, high ceramic yield, good adhesion to materials like metals, ceramics, and graphite, and it is easy to prepare SiBCN ceramics. These properties enable it to perform excellently in many fields, including ceramic matrix composites, metal matrix composites, high - temperature adhesives, and anti - corrosion coatings.

With the continuous development of technology, the demand for high - performance materials is increasing day by day. The emergence of organic polyborosilazane IOTA 9120 provides new ideas and solutions for solving problems such as high temperature and corrosion, and is expected to play an important role in more fields in the future, promoting the development of the materials industry.
