The preparation technology of silazane is difficult, the composition of reaction products is complex, and the preparation cost is high.
Polysilazane has very high reactivity to water, heat, oxygen, polar compounds, etc., and is difficult to store and transport.
A large number of application scenarios are still in the exploratory stage, and the high application cost is not conducive to promotion.
It is difficult to obtain special silicone monomers required by various polysilazanes, which cannot meet the diversified needs of product functions in different application scenarios.
