01. All-Round Protection of Polysilazane

Car bodies retain their shine even after being exposed to wind and sun, with every detail—wheels, front, and rear—shining brilliantly thanks to the all-round protection of polysilazane. Similarly, the pristine cleanliness of sinks, marble slabs, train carriages, and shop facades is also inseparable from the remarkable effects of polysilazane. Its excellent stability provides long-lasting protection for various materials, keeping their beauty looking new for longer.

02. Unique Properties and Composition of Polysilazane

► Composition and Classification

Polysilazane originates from the innovative path of silicon polymers. Its core components include silicon and nitrogen, incorporating hydrogen and carbon elements to construct a unique molecular framework. This product is divided into two main series: organic polysilazanes, such as LS-PA150 Rapid Cure and LS-PA150 Slow Cure, both with 100% effective content; and inorganic polysilazanes with an effective content of 20%.

► Curing Characteristics

Polysilazane exists as a transparent, low-viscosity liquid, making it ideal for solvent-based systems. It cures at room temperature via moisture or heat, producing coatings that are either silica-like (similar to quartz glass) or ceramic-like. These coatings are dense and transparent, providing excellent protection for the substrate. Furthermore, polysilazane resin forms a strong covalent bond with the substrate surface, exhibiting excellent adhesion to most substrates, including metals, glass, stone, ceramics, plastics, composites, wood, and varnishes.

03 Applications and Benefits of Polysilazane

► Wide Range of Applications

Polysilazane demonstrates numerous outstanding benefits in applications: it possesses excellent high-temperature resistance, enabling it to withstand harsh environments; simultaneously, its corrosion resistance and aging resistance are extremely excellent, ensuring long-term stability. In addition, polysilazane exhibits excellent scratch resistance, impact resistance, and abrasion resistance, allowing it to maintain excellent physical properties in various environments. Its chemical resistance is also excellent, resisting the erosion of various chemicals. In terms of hardness, depending on the formulation and substrate, organic polysilazane can reach 5H, while inorganic polysilazane can reach as high as 9H, providing robust protection for the substrate. Furthermore, the strong hydrophobicity of polysilazane makes the surface easy to clean, and its low film thickness and high efficiency provide durable and long-lasting protection for the substrate.

Polysilazane resins have wide applications in many fields. In transportation, it is widely used for surface protection of automobiles, high-speed trains, ships, and aircraft. Simultaneously, polysilazane plays an important role in the surface strengthening of building materials, kitchen appliances, wind power, and high-precision optical glass. In addition, it is used for waterproof protection of components in consumer electronics products such as computers, communication devices, and mobile phones, providing excellent protective performance for electronic products.
