High-performance coatings require not only good adhesion and weather resistance but also excellent water resistance and long-term stability. To meet these requirements, many coating systems utilize functional fillers treated with HMDS (hexamethyldisilazane).

HMDS imparts excellent hydrophobic properties to fillers, thereby reducing the coating's water absorption and enhancing its weather and corrosion resistance.

Additionally, HMDS-treated powders disperse more uniformly, helping to improve surface smoothness and mechanical properties. These characteristics are particularly critical for anti-corrosion coatings, high-temperature resistant coatings, and electronic protective coatings.

With the growth of sectors such as new energy, rail transportation, and marine engineering, the demand for high-performance coatings continues to rise, further expanding the market potential for HMDS as a key surface modification material.
