Used as an adhesion promoter and crosslinking agent in moisture-curing silicone sealants and coatings. Enhances durability and adhesion to substrates like glass, metal, and plastics in construction and automotive applications. Provides improved resistance to weathering, UV exposure, and thermal cycling. Commonly found in sealants for windows, joints, and gaskets where long-term performance and flexibility are required. Also helps prevent premature curing by acting as a hydrolysis stabilizer during storage.
