Used as a hydrophobic agent in coatings and sealants due to its ability to repel water effectively. Acts as a surface modifier in silica-based materials, improving dispersion in non-polar solvents and polymers. Employed in the synthesis of organosilicon compounds for specialty chemicals and intermediates. Serves as a precursor in sol-gel processes where controlled reactivity and low polarity are required. Also utilized in electronic encapsulation materials to enhance moisture resistance and thermal stability.
