The coating made of polysilazane has the following characteristics:
Excellent high temperature resistance: Polysilazane can be converted into silicon nitride ceramics under high temperature conditions, and can withstand a temperature range of -50 ℃ to 1800 ℃, which can meet some application scenarios with extremely high temperature resistance requirements, such as protection of related components in aerospace, metallurgy and other fields.
Good corrosion resistance: Polysilazane coating can effectively resist the erosion of acid rain, salt water, alkaline solution, etc. Its molecular structure is stable and can form a dense protective layer to prevent corrosive substances from contacting the substrate. For example, in marine or chemical environments, the use of polysilazane coatings can extend the service life of equipment.
High hardness and wear resistance: Polysilazane coatings have excellent surface hardness, scratch resistance, and wear resistance. After curing, the hardness can reach 8H or above, and it performs well in pencil hardness testing. It is not easy to scratch or wear in long-term use, and can maintain good surface condition. It is suitable for components with high surface wear resistance requirements, such as automotive engine components, mechanical parts, etc.
Good weather resistance: Polysilazane has the heat resistance and weather resistance characteristics of Si silicon element, as well as the antioxidant, anti-aging, and chemical inertness characteristics of N nitrogen element. It can resist the erosion of natural factors such as ultraviolet radiation and acid rain, and is not easily faded or aged when exposed to outdoor environments for a long time. It can be used as a protective coating for outdoor buildings, bridges, and other facilities, reducing maintenance costs.
Easy to clean: Coatings based on organic polysilazane have hydrophobicity, with a water contact angle in the range of 95 ° -105 °. Their low surface energy gives them excellent non stick, anti graffiti, and easy to clean properties. They can easily remove surface stains with water or simple cleaning agents, maintaining the appearance and hygiene of the coating. They are suitable for coating surfaces such as building exterior walls and kitchen and bathroom facilities.
Good adhesion: Polysilazane has good adhesion to various substrates such as metals, ceramics, and polymer materials, and can firmly adhere to the surface of objects without easy detachment, ensuring the long-term effectiveness of the coating. It can be applied to surface protection of objects of different materials.
Good insulation: With high electrical resistivity and dielectric strength, it can be used as an insulation coating in fields such as electronic circuits and semiconductors to ensure the safe operation of electrical equipment.
Strong processability: It combines the plasticity and processability of organic matter, and is easy to apply through methods such as spin coating, wipe coating, spray coating, and dip coating. It can be made into various shapes and thicknesses of coatings according to different application requirements, meeting diverse production process requirements.
