1. High cost
Overall, raw material prices will be in a volatile state, increasing the uncertainty of industry costs, and sometimes even leading to high costs. At the same time, labor costs have risen, and high labor costs have brought greater cost burdens to manufacturers.
2. The preparation technology is difficult
At this stage, there are still technical bottlenecks in the global preparation process of polysilazane, and the nature of polysilazane is more active, storage and transportation is more difficult, so the market size of polysilazane is small compared with similar polymer polysiloxane.
3. Patent blocking
There is still a big gap between China's comprehensive competitiveness of polysilazane and that of developed countries. The excellent processing properties and product properties of polysilazane coating make it have broad application prospects. In terms of the preparation of polysilazane, China's comprehensive strength is weak, and for the application of polysilazane coating, applicants from developed countries such as AZ Electronic Materials, Samsung Co., LTD., Konica Minolta Co., LTD., Linde Co., LTD., have carried out patent layout in China early, and the number of patents is large.
Compared with the research on polysilazane coating abroad, there are few research reports in China, and there are few reports on the application of polysilazane in the field of optoelectronics, which undoubtedly poses a challenge to the development of China's polysilazane industry. China should strengthen the research on the preparation method and application method of polysilazane, break through the difficulties in the preparation and application of polysilazane, strengthen the protection of intellectual property rights, and build a competitive polysilazane coating industry chain.
