Advantages of organosilazane as coatings

1. Close adhesion with metal, glass, mineral, ceramic and organic materials and other substrates;
2. Characteristic physical properties: high hardness (9H+), UV transparency, corrosion resistance, heat resistance and thermal stability, etc.
3. Excellent coating film, can be used in different environments, high temperature resistance, excellent weather resistance and chemical resistance.
Industrial chain
1. Raw material supply
The main raw materials of polysilazane are silicon, nitrogen, hydrogen and other elements, among which silicon and nitrogen are the key raw materials for the preparation of polysilazane. The supply of silicon and nitrogen mainly comes from mineral resources and chemical raw materials, such as silica and ammonia.
2. Preparation technology
The preparation technology of polysilazane mainly includes chemical vapor deposition (CVD) and other methods. CVD is a method of decomposition and deposition of gaseous precursor substances on the substrate at high temperatures, which can prepare high-quality polysilazane films.
3. Application field
Downstream applications of polysilazane include manufacturers and research and development institutions in semiconductor, optoelectronics, aerospace and other applications. At present, coating materials and resin materials are the main application areas of polysilazane. Polysilazane can be converted into ceramic materials by high-temperature pyrolysis, and is an important ceramic precursor. With the rapid development of the new material industry and the growing demand for ceramic-based materials, its market space is constantly expanding. At present, the main applications of polysilazane are:
Silicon nitride, silicon boron carbon nitrogen and other ceramic fiber precursors
Heat-resistant coating
Metal high temperature and corrosion protection
Super precision ceramic parts adhesive
High temperature resistant composite material modification
Photoresist viscosifier
Lithium battery electrolyte additive
Carbon fiber oxidation resistant high temperature resistant coating
Anti-graffiti coating for transportation vehicles and buildings
Kitchenware ceramic non-stick coating
Self-cleaning coating for photovoltaic cells
Non-combustible composite material
