Used as a surface modifying agent to impart water repellency and improve adhesion properties in coatings and sealants. Commonly applied in the treatment of silica fillers for silicone rubber to enhance dispersion and compatibility. Also utilized in the synthesis of specialty siloxane polymers for use in personal care products, where it contributes to smoothness and spreadability. Its reactivity makes it valuable in creating moisture-curable systems that form durable, hydrophobic films upon exposure to atmospheric moisture.
