Used primarily as a surface modifier in silicone-based formulations, this compound enhances water repellency and improves adhesion properties in coatings and sealants. Its reactive silanol groups allow it to bond effectively with inorganic substrates like glass, metal, and ceramics, making it valuable in primers and coupling agents. It is also employed in the synthesis of specialty silicones for personal care products, where it contributes to smooth texture and stability. Additionally, it finds use in modifying silica fillers for high-performance elastomers, improving dispersion and mechanical properties.
