Used as a crosslinking agent in silicone-based coatings and adhesives, enhancing thermal stability and moisture resistance. Commonly applied in electronic encapsulants and protective films due to its ability to form dense, flexible silica networks at low temperatures. Also utilized in sol-gel processes to produce hybrid organic-inorganic materials for optical and anti-reflective coatings. Its hydrolytic stability and low viscosity make it suitable for precision casting and thin-film applications.
