Technical bottleneck: The preparation technology of polysilazane is difficult, and the composition of reaction products is complex. Further breakthroughs are still needed in the preparation process in China to improve product quality and production efficiency.
Patent barrier: Foreign companies have already established patent layouts in China in areas such as polysilazane coatings, with a large number of patents, which limits the development space of domestic enterprises.

Raw material supply: It is difficult to obtain special organic silicon monomers required for various polysilazanes, which cannot meet the diverse functional needs of products in different application scenarios.

Storage and transportation: Polysilazane has extremely high reactivity towards water, heat, oxygen, polar compounds, etc., making storage and transportation difficult.
