Used as a cross-linking agent in silicone curing systems, especially in moisture-cure sealants and adhesives. Enhances flexibility and durability of silicone coatings by forming stable siloxane bonds upon hydrolysis. Also applied in sol-gel processes to modify surface properties of glass and metal substrates, improving adhesion and water repellency. Its dual silyl functionality allows for efficient network formation in hybrid organic-inorganic materials.
