In the field of advanced materials, finding a material that combines the dual functions of a thermosetting resin and a ceramic precursor is no easy task. Organopolyborosilazane (Ceramizable Precursor Polymer) IOTA 9120 is undoubtedly an outstanding option.

IOTA 9120 is a liquid precursor polymer composed of repeating Si - N units and Si - N - B units. It can be cross - linked and cured into a thermosetting resin at 120 - 180℃ in air or an inert atmosphere. It can also be cured through a hydrosilylation reaction using a platinum catalyst at 80 - 100℃, with a curing time of 2 - 5 hours, offering flexible curing options.

This material boasts remarkable characteristics. It has low viscosity, making construction convenient; short curing times for high efficiency; and diverse curing methods to meet different needs. It has a high ceramic yield and good adhesion to metals, ceramics, and graphite. It is easy to prepare SiBCN ceramics with good temperature resistance. After high - temperature pyrolysis, it forms amorphous ceramics below 1600℃ and starts to crystallize above 1600℃. The composition of the ceramic products is closely related to the pyrolysis atmosphere.

In terms of technical parameters, it is a light - yellow liquid with a solid content of 99.9%, a molecular weight (Mn) of 700 - 900, a viscosity of 10000 - 20000 cp, and a ceramic yield of the cured product (at 800℃) of over 50%. The ceramic density is 1.70 - 2.00 g/cm³.

In application areas, IOTA 9120 is widely used in ceramic matrix composites, metal matrix composites, high - temperature adhesives, anti - corrosion coatings, and more. Choosing IOTA 9120 means choosing a high - performance and multi - functional material to provide solid support for your projects!
