Polysilazane (PSZ) is an emerging material known for its unique ceramic conversion and protective properties. When cured or heated, it transforms into a dense Si–O–Si or Si–N–Si network, creating a coating that resists heat, corrosion, and oxidation.

In the automotive and aerospace industries, polysilazane coatings are applied to exhaust systems, engine components, and metal parts to improve thermal durability and surface hardness. They also provide excellent adhesion and chemical stability, ensuring long-term protection even under extreme environments.

In addition, PSZ is used for anti-fouling, hydrophobic, and transparent protective films on glass and electronic components. These coatings maintain optical clarity while shielding against moisture and dust.

As industries move toward high-performance and eco-friendly materials, polysilazane stands out for its versatility, durability, and environmental benefits.
